Control Charts Made EASY! Copyright (c) 1989 Mark H. Libert All Rights Reserved Control Charts Made EASY! is an interactive BASIC program designed to let your IBM or compatable computer take the place of a hand calculator when making common calculations from control charts. Control charts are used for statistical process control throughout the manufacturing industry. Many companies handle SPC data electronically from measurement to computer generated charts. Others use partially computerized systems, or they perform SPC manually. Unless a system is 100% computerized and no calculations are made by the operator or inspector, Control Charts Made EASY! will simplify the use of the control chart. The chance for operator error is eliminated when the computer calculates a complex formula typical to statistics. Control Charts Made EASY! will calculate control limits for the following charts: _ x & R Average and range median charts x & s Average and standard deviation individuals and moving range p charts c charts np charts u charts It will also calculate Cpk, CP, and CR for the variable data charts. It will calculate Cpk from mean and standard deviation, and calculate P-C line values for pre-control / stoplight control charts. Control Charts Made EASY! is simple to use, and has many features to check for errors in data entry or incorrect use of a chart. USE THE HELP FEATURE OFTEN when operating the program. There are fifteen different screens of help and information to assist with operation and describe the uses of each chart type. Using Control Charts Made EASY! is not difficult and each chart section operates in a similar fashion. Prompts for part number and check- point number begin each section. Entering a number or name in these places will cause them to be displayed with the calculated results. If you do not wish to enter anything in these places, simply strike the ENTER key when prompted. You will then be prompted to enter other information needed to calculate control limits for SPC charts such as subgroup size, number of subgroups, lot sample size etc. Once these things have been entered, the entering of data can begin. Prompts on the screen always help you to know what to do next. Once the data has been entered, control limits will be displayed instantly if you choose; or enter specification limits to also calculate and display Cpk, CP, and CR. At almost any point of the program, the <E> key will help you back up or get out. An E to Exit sign at the bottom of the screen appears most of the time. When it does not, the <E> key might still help out. Here's how. When entering data, mistakes can be made. That's normal. If you look at the screen and see you have made an error, enter an E in place of any next data. At that point, you have entered the error recovery route. You can then choose to go back to any point and resume. Control Charts Made EASY! does not make charts, but will make all the calculations needed for making SPC charts. If a hand calculator is ever used for control chart calculations, Faster, easier, more dependable results can be obtained by using the computer. Control Charts Made EASY! is protected under the copyright laws and registered with the Library of Congress. It is prohibited to edit Control Charts Made EASY! or distribute it for profit. You are, however, encouraged to distribute it freely to anyone who might benefit from its use. Libert Computer Systems 2655 Fox Rd. Greenville, OH 45331 1989

E G r a p h ENGINEERING GRAPHICS Copyright (c)1987-91 by Great Basin Associates 653 Ave M Boulder City, NV 89005 EGraph is a technical graphics program for the IBM-PC with a CGA, EGA, VGA color or mono, MCGA, or Hercules card. LINEAR, LOG, PROBABILITY, and TIME SERIES axis scaling may be mixed. Over 32,000 x,y data pairs may be graphed. Descriptive Statistics, Histogram, Cumulative, Frequency, Mass, Moving Avg Distributions, Polar, Pie, Bar, HiLoClose, Triangular Percent, Regression, Pearson III, Splines, and Contours can be added. Text lines, curves, and points can be interactively placed on graph. Data can be read directly from Lotus worksheet files, PRN, columnar ASCII files or keyboard. Graphs may be printed directly on an Epson, HP LaserJet, HP Plotter, or saved as a Lotus PIC file. High resolution graphs can be printed or plotted using all the printers and plotters supported by Lotus 123 or Symphony. The PIC file can also be imported into other programs such as Freelance, Word Perfect, Word and desktop publishers for editing and printing. It is menu driven with pulldown & pushbutton selection. After reading the command line and data format sections below, users may not need to read the rest of this manual before starting. Single drive users may replace the EGraph disk with a data disk. EGraph COMMAND LINE: Options can be set when starting EGraph by including values for setting screen foreground and background colors or auto selection of graphics adapter or data file. The command line format is: EGRAPH,a,b,c or EGRAPH filename (command line format) The default values used when only EGraph is entered from the DOS prompt is: a= 1 color blue foreground b= 7 color white background c= 0 auto selection of graphics adapter, 1 for manual For example, EGraph,4,7 would set red on white screen colors with auto select type of graphics adapter. Color numbers are: 0-Black, 1-Blue, 2-Green, 3-Light Blue, 4-Red, 5-Violet, 6-Brown, 7-White: Add 8 to these values for brighter foreground color. 1 EGraph MENU OPTIONS FILE: Input data files can be created from any program that creates ASCII files or from Lotus Worksheet files (WKS, WK1). Most word processor programs can create ASCII files but usually is not the format in which they normally save files. Each line of data is terminated by the carriage return (ascii 13) and linefeed (ascii 10) sequence. These terminate each row of data but will not be displayed when using the TYPE filename DOS command. TAB's(ascii 9) are read as 1 character and not expanded into 8 spaces as displayed using the TYPE command. You can check for TAB's using the DOS command COPY /B filename CON. This displays the file in binary format on the screen and TAB's show up as little circles. This should be kept in mind when telling EGraph where data columns are located. The included utility program NOTABS will read a file and replace the tabs with 8 spaces. To use NOTABS type NOTABS infilename outfilename. Below are data files in EGraph's default data locations of 9 characters wide starting in column 1. If your data is not in this format or data is row wise sequential then answer "Y" to the Change Default width, starting column, and # of variables/row. A data file can have as many title lines as desired. EGraph will detect the beginning of data when the line contains only numbers. Lotus 123 users can create columnar ASCII files by using / Print File Range Options Margins Left 1 or 0 Other Unformatted. EGraph DATA FILES Example of 1 Y variable data file Title lines are ok. Y1 'Y1 is not required and is used for clarity here 12.1 10122 'Y data without an X is useful for time series data 9.999 'or probability and cumulative distribution 1.23E-6 'scientific notation ok! Example of 1 X and 1 Y variable data file X1 Y1 .99 2222 .999 589 .9999 -98.4 'X values may be user computed probabilities 2 Example of 2 Y variable data file Y1 Y2 3.03333 4343.34 1.0E-38 1.0E+38 'values from +- 10 to the 38th power. 2322 1231 'range limit of 1E+38 Example of 1 X and 2 Y variable data file X1 Y1 Y2 -233 444 3.222 1234567 2.098456-12.34567 'up to 7 significant figures 123456789 44.3 9.982 more are rounded: 1.2345679E+08 Example of 2 X and 2 Y variable data file X1 Y1 X2 Y2 obs close hi lo ''or Hi/Lo/Close 1 33.125 35 30 2 23 33 22.5 3 23.5 26 22 Example of 7 X,Y sub variables X1 Y1 1 1 2 2 'a blank or letters in Y1 or Y2 will cause 1 2 a start of a new line to be drawn. This is 2 3 useful for displaying more than 2 lines. Digitized lines can be graphed as was done 1 3 for the map of western U.S states example. 2 4 Confidence limits may be read in as X2,Y2 values with a blank line to separate upper 3 -6 and lower limits. Several confidence levels 22 13 can be added in this manner. Each line for .1 -9 Y2 values will be graphed in a different color or dash style when a blank Y2 value is 5 8 encountered. This allows more than 2 6 9 variables to be graphed with different line styles (see EXAMPLE3.DAT file). # of blank 7 7 blank values before new line can be set 9 4 12 12 15 5 The included utility program PRNWHAT can be used to read your original data file and extract data into columns for EGraph if your data file is not in the above form. Lotus worksheet files (.WKS or .WK1) may be read by simply entering the entire worksheet filename with the .WK1 extension and EGraph will know to read the file as a Lotus or Symphony worksheet file. You will be prompted to select a X1, Y1, X2, or Y2 variable and the worksheet range to be read into it. For 3 example, to read the first 20 values in column A, you would enter "A1..A20" as the start and end of the data range to read into the variable. To read rowwise use "A1..L10" to read row A1..L1, A2.. L2, etc. Several data ranges in the worksheet can be repeatedly selected for entry into one of EGraph's variables in order to graph several data ranges. When you save your Lotus worksheet, you must remember what ranges your data to be graphed is in. File names may use DOS wildcard characters * and ? to help locate files. B:*.dat, Test?.*, \data\project1\cost*.* are legal file names. The files matching the filename mask will be displayed and you may then select your filename choice for data reading. Select FILE, sHell for temporary exit to DOS. Type EXIT to return to EGraph from DOS. The file COMMAND.COM that comes with DOS must be in your boot drive. EDIT: Data can be entered or edited from the keyboard and saved for rereading. A blank cell for Y1 or Y2 values will start the beginning of a new line to be drawn so that 100's of line segments or variables can be graphed. Data entry is terminated by hitting the Escape key. If Y2 values are entered, you may select to either graph them or use them as labels for Y1 values. Editing keys are: Escape....Exit editor Space.....Delete cell contents Insert....Insert cell in data column Ctrl-Y....Remove cell in data column Delete....Delete character Enter.....Enter displayed value and move down 1 cell Arrow.....Move left, right, down, or up 1 cell PageUpDn..Move 1 page Home......Move to top of column End.......Move to end of column F1........Swap X1-Y1 with X2-Y2 F2........Copy pointer X-Y to other X-Y F3........Swap pointer X with Y F4........Copy X1 to X2 F5........Undo edit +.........Begin Math: +x<operator>y [;N] Select EDIT, Fill to fill a data column using start-step-stop. Use fill X2 to supply values for interpolation under STATS. For MATH use the editor Alt*H help screen for examples. PLOT: Graph Titles, Axis Labels, and Scaling: After the data values are edited, select PLOT, Titles, Graph type or Scaling for desired settings. Press escape from within one sub-menus to exit back to the main menu line: Select PLOT, Plot to view and edit graph. Press Alt*H for help in graph editing. Once your graph is setup, you may save the current settings and 4 and titles to file for future use (FILE, sAve setup). The setup files may be edited outside EGraph for easy updating. Select PLOT, Manual scaling for setting of the X and Y axis scale range. The Y axis may be inverted to graph such things as depth using positive values. Display of the X axis values may be sup- pressed so that you may add your own labels. A second Y axis for Y2 values may be added. Time series plots with blank rows in the Y2 column may be reset to start of the time scale for graph- ing several variables using a time series X axis. Select PLOT, Auto scaling to reset EGraph's default settings. Select PLOT, Plot to view and edit the graph. Use the arrow keys to add text, symbols, straight lines or curved lines. You may also get the cursor coordinates. The cursor is moved using the arrow keys or Left Shift*Arrow keys together for small moves. After moving to a location begin entering text and terminate with the Enter key. The last line, symbol, or text type added can be deleted with the Delete key. To switch type of editing to delete enter that type anywhere on the screen and then proceed deleting that type one at a time with the Delete key. When finished, press the ESC key to exit. Graphic editor keys are: Escape...........End editing & return to main menu Arrow............Move cursor left, right, up, down 8 pixels LeftShift-Arrow..Move cursor 1 pixel Enter or arrow...Enter text string being added F1...............Add a marker F2...............Start and end a dashed line F3...............Start and end a straight line F4...............Mark 3 points on a curved line F5...............Toggle display of cursor x and y coordinates F6...............Increase editing color, line & marker type F7...............Decrease color, line & marker type Delete...........Delete last text, marker, or line type added Alt-H............Help Graph Printing and Lotus PIC Files: After viewing & editing the graph, select PLOT, File to print the graph. The EPSON option will print your graph as half, full, or manually set size directly on an Epson compatible printer installed on the LPT#1 port. Either Epson FX (9 pin) or LQ (24 pin) type compatible printer may be used. The HP-LaserJet is also supported directly or sent to file. The LaserJet file can be sent to a LaserJet later using Copy /b filename PRN. The Lotus PIC file option creates a high resolution file that can be graphed or plotted using Lotus' or Symphony's PGRAPH.EXE program. When naming your graph file add the extension .PIC so PGRAPH can locate it. The enclosed graph examples were plotted 5 using Lotus PGRAPH.EXE and an HP lasor printer. Other programs like Freelance, Word Perfect 5, and desktop puplishers can import the PIC file for editing and printing. Although not displayed properly in EGraph the Lotus LICS extended character codes can be used as text by holding down the ALT key & entering the code number on the NUMBER PAD only. Single floppy disk system users should remove the EGraph disk after loading EGraph and replace with a data disk. The EGraph distribution disk does not have enough disk space for creating graph files. The HPGL plotter option requires disk space for creating a temporary disk file before sending the graph to a plotter. STATS: STATS, Stats: Descriptive statistics for each of the variables can be displayed and include Sample Size, Mean, Median, Min, Max, Variance, Std. Deviation, Std. Error of Mean, Skew, and Kurtosis. STATS, spLine: A smooth curve can be fit to X1,Y1 points by computing X2,Y2 points between the X1,Y1 input data points. Examples of the use of this spline fitting is for interpolating points between rainfall depth-duration data or reservoir elevation-area-capacity data. The X2,Y2 points are interpolated by weighting the tangents of the lines connecting the X1,Y1 data input points to create a smoother curve through the points. The number of interpolated points between input points are user defined. The number of computed points between the input values is limited to 16,000. STATS, Interpolation: Interpolation & extrapolation using linear, log, & probabilty scaling to compute Y2 value from X1-Y1 lookup of X2 value. Enter selected lookup points as X1-Y1 and use EDIT, Fill, X2 to provide a range of values for interpolation. STATS, Distributions: A frequency histogram will show how many of the Y1 values are in a class (interval or bin) displayed on the X axis. All Y1 plot options should be set to N except Bar Graph. A normal frequency curve will be fit to the Y1 values and can be turned off or on using the Y2 plot settings. A better aid in checking to see if your Y1 data is normally distributed is to use Probability with the Pearson III option with 0 skew. Normally distributed data will plot as a straight line on normal probability paper. The cumulative percent distribution of Y1 and Y2 values may be computed and graphed. The formula used to compute each Y values X plotting percent value is 100*Rank/N for percent of values less than or equal to and 100*(1-(Rank-1)/N) for percent of values greater than or equal to. The X values in the original data will be replaced with the cumulative percentage values. If the Spline 6 or Regression options are used after the cumulative percent then the X values used will be percentages. The cumulative distribu- tion is useful for viewing how your data is distributed. For example, daily streamflow cumulative distribution may be viewed to see what percent of the time flow is below a certain value. Log X axis scaling or probabilty scaling may be used to expand the lower percentage values. Y1 and Y2 cumulative distributions can be graphed together for comparisons. Mass curves are a cumulative sum of Y1 data usually with time. Changes in slope of the mass curve can show a change in the relation with time. A double mass curve is a cumulative sum of both X1 and Y1 data to show changes in their relation. Sometimes it is helpful using a double mass curve to use the average of several variables as X1 values to limit variability. Regression errors plotted as a residual mass curve can help magnify changes in the variables relationship. STATS, Regression: A regression line can be added to either the X1,Y1 or X2,Y2 data. The regression coefficients a and b, R squared, and standard error of regression can be displayed on the graph. Selecting regression does not alter the original X,Y values. When using Log10 transforms of the Y values (options 3-5), the R squared value is for untransformed values, not log values and the standard error of regression is given in percent. X,Y data must be greater than zero to compute Log10 transforms. Y=a+b*X will be a straight line with linear axis scaling and Y=aX^b will be a straight line with log axis scaling. An offset value e may also be added for regression of Y=a(X+e)^b. This is useful for data that is not linear on log-log paper. The offset value "e" can be selected if an arbitrary base or datum is known to have been added to the X range values. Otherwise, for curved data sets, the "e" value can be determined by trial and error and noting the R^2 and Standard Error values. The point of zero flow for water discharge ratings with arbitrary datums is an example of regression of data requiring an X offset value. Caution should be used in extending regressions outside the range of data and near zero, especially option 2, Y=a+bX+cX^2. This is a parabolic curve and can reverse direction. The X1-Y1 regression residuals can be plotted as Y'-Y, predicted Y minus data Y. Error plots that show a trend or pattern may indicate the need for a different regression type or transform of the original data. STATS, Probability: A normal probability graph or a log-normal probability graph of the Y1 or Y2 values may be made by selecting either linear or Log Y axis scaling. The non-exceedance probability X axis values (plotting position) are computed by Rank/(N+1) and exceedance 7 values are computed by 1-Rank/(N+1). The X values in the original data set are replaced with the probability values if read. Spline or Regression used after Probability will be based on probability X values. Probabilities for the X axis may also be computed by the user and read in as X values so that other plotting position formulas are possible. Upper and lower confidence limits may be computed by the user and read in as X2,Y2 values and separated with a blank line to start a new line. Probability graphs are similar to Cumulative Distribution graphs and can be used for similar purposes. Probability graphs can be used to view what data lies within a given number of standard deviations. Changes in the slope of the probability curve can show mixed populations in the data. Normally distributed data plots as a straight line on normal probability paper and log- normally distributed data plots as a straight line on log-normal graph paper. The Pearson or Log-Pearson Type III distribution can be fit to the Y data by computing the mean, standard deviation, and skew of the Y data or Log10 transforms. The Pearson Type III deviate K for a given probability is then computed based on the skew and the Y for that probability is computed as Y=mean+std.dev.*K or Log10(Y)=mean+std.dev.*K. The Pearson III distribution with zero skew is the normal distribution. The Log-Pearson III distribution with zero skew is the log-normal distribution. The Pearson III option does not replace any of the original X,Y data. The Log-Pearson Type III distribution is used extensively in low- flow and flood frequency hydrologic analysis. A complete frequency analysis program using the Log-Pearson Type III distribution is available from Great Basin Associates. The Pearson III distribution may fit the Y data better when high negative skew is found by the Log-Pearson III (data more normally distributed). Some annual series such as high 15-day runoff volume may be more normally distributed and fit better with the normal distribution. TIME: The Y1 and Y2 values may be graphed as an evenly spaced time series. The X1 or X2 values are not needed and are changed if read. The general time series can be used to graph any evenly spaced data. Contour & Surface Plots of X,Y,Z data: The included utility program CONTOUR.EXE may be used to create contour & surface plots with EGraph. CONTOUR reads random X,Y *****MANUAL CUT SHORT DUE TO DISK SPACE***** 8
P C - S I G ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Welcome to the world of Shareware, state of the art software you can actually try before you buy. Shareware, a term coined in the early eighties, refers to the method of distribution chosen by the software authors. With shareware, you can receive a program and put it through its paces without having to pay for it. If you find the program useful, and choose to keep the program, then you pay a registration fee to the author. However, if the program does not fit your needs, there is no obligation to send the registration fee. It's that simple For the last nine years, PC-SIG has been providing shareware and public domain software to its customers and members. Since 1982 PC-SIG has developed an unprecedented library of shareware programs, constantly updated, consistently strong in every category. Our library of shareware contains over 2700 titles divided into 120 logical categories. Every program we add to the library is thoroughly reviewed and tested to ensure that each one meets the high standards of reliability and value we insist upon and you expect. As a result, our library doesn't contain every shareware program available, just those that really work. PC-SIG has grown into the premier distributor of shareware and and shareware information by producing shareware collections on CD-ROM, publishing an encyclopedia of shareware, and by publishing Shareware Magazine, a bi-monthly magazine distributed world-wide. Quality and support - guaranteed. All of our programs are guaranteed virus free. We've isolated our systems and checked every program submitted to ensure that no viruses make their way to your computer or ours. Our support staff is available by phone as well as on our BBS to help you with questions about installation and operation of PC-SIG's products. Through our network of international distributors, PC- SIG strives to bring you the most current, exciting, technically advanced software available as shareware.
