VINNY GRAPH v1.61 for Pocket PC and Pocket PC 2002 INTRODUCTION Vinny Graph for Pocket PC is a quick flexible XY graphing program which can generate a series of different graph types. It is easy to use and accepts and exports data through a variety of sources. Data can be entered manually into a mini spreadsheet. It can also be pasted into the spreadsheet from other applications such as Excel. Complete graphs can be loaded from [.vin] graph files. The [.vin] files can also be imported from desktop Vinny Graphics by translating [.gra] files. This process works in both directions so that files generated on the pocket PC can be viewed on a desktop PC or vice verse. INPUT Data input is by: 1-Cut, copy and paste from external spread sheets. 2-Key pad entry into a mini internal spread sheet. 3-Loading complete graph files with [.vin] extension. OUTPUT Output is by: 1-Cut, copy and paste to external spread sheets. 2-Copying value of the regression coefficients. 3-Copying Y interpolation values. 4-Saving complete graph files with [.vin] extension. GRAPH SETTINGS Graphs allow total freedom in setting up scales and grids. Direct inut of values for Xmax, Xmin, Ymax and Ymin. Set X grids and Y grids form 1 to 20. Graph types include points, lines, bars, lines & bars and linear, 2nd order, Log and power regression fits. MATH AND REGRESSION An interpolation window accepts X value inputs and provides an estimate for Y using a straight line connecting the XY points. It also provides Y estimates using the following: 1- linear regression fit. 2- 2nd order regression fit. 3- log regression fit. 4- power regression fit. The values for the regression coefficients along with the coefficient of determination are dislpayed and can be copied. COMPANION TO DESKTOP VERSION VINNY GRAPHICS 2.02 A drag and drop file conversion utility is included with the ZIP package. Vin_Gra.exe runs on a desktop PC and converts files in both directions. If a pocket pc [.vin] file is dragged and dropped onto the Vin_Gra.exe icon a desktop Vinny Graphics [.gra] file is produced. If a desktop PC [.gra] file is dropped on the icon a [.vin] Vinny Graph pocket PC file is produced. The desktop PC can thus be used to print pocket pc generated graphs. Note pocket pc Vinny Graph files are restricted to one data set. FILES IN THE ZIP PACKAGE This zip package contains the complete Vinny Graph Pocket program with Setup.exe for instillation. CAB files for the following processors are included. 1-SH 3 (1K) v3.00 2-Mips 4000 (4K) v3.00 3-Arm 1100 (4K) v3.00 4-I486 (4K) v3.00 After instillation six demo graph [.vin] files can found in the pocket pc personal folder. 1-DemoLine.vin 2-DemoBar.vin 3-DemoLinear.vin 4-Demo2nd.vin 5-DemoLog.vin 6-DemoPower.vin The drag and drop conversion utility Vin_Gra.exe is also in the ZIP package along with this readme file readpock.txt. PROGRAM HELP (Just tap [Window|Help] at any time) 1-DATA ENTRY Use [Window|Data] to manually enter XY data points into mini spreadsheet cells. To select blocks of data, drag over the cells. To copy, paste or delete selected data tap the icons at the bottom of the data window. Copied data can be transferred to and from other programs such as Microsoft Excel. After data entry, but before viewing graph, tap [Window|Settings] and [Auto Scale]. This assures that all data points are in the range of the graph. Save graphs using [File|Save] and load graphs using [File|Open]. Use [File|New] to clear data and reset settings to default values. 2-SETTINGS Use [Window|Settings] to selected the graph type. Tap the desired radio button. Graph options include points, lines, bars and linear, 2nd order, log and power regression fits. Tap [Auto Scale] to set the scale values for Xmax, Xmin, Ymax and Ymin. [Auto Scale] also sets XY grid values. Modify these initial settings as desired. If data values are changed rerun [Auto Scale]. Edit graph titles as desired. 3-INTERPOLATE and REGRESSION Use [Window|Interpolate] to estimate values of Y given X and to select the best regression fits. Input individual X values into the top text box. Tap [Interpolate] to estimate a corresponding value for Y. Both a straight line and a curve fit estimate are provided. Tap the desired regression type to change the curve fit equation. Use the coefficient of determination to select the best fit. The best values are less then but nearest to one(1). Tap to copy Y estimates or regression coefficients to the clipboard. Note the current graph type is automatically switched to the selected regression equation.
