               WPlot Description and Installation Instructions

    WPlot is a 32-bit Windows program that plots two and three-dimensional
    data.  Up to 250 sets of data can be plotted on the same 2-dimensional
    plot using either one or two vertical axes.  There can be up to 131072
    data points per data set.  Each data set can be plotted as a line plot, a
    smooth curve plot, a scatter plot, a step plot or a histogram.  Multiple
    data sets can also be plotted as a 3-dimensional plot.   The plot can
    have linear or log axes with auto or manual scaling.  Two-dimensional
    plots can also have cumulative normal probability axes, error bars and
    descending as well as ascending axes.  Data can be fit by a smooth curve
    or a least squares polynomial or exponential.  The Fast Fourier Transform
    can be used to fit the data with a discrete Fourier series and the
    magnitudes of the FFT coefficients can be plotted.  Mathematical
    transformations of the data can be performed by entering equations that
    operate on one or more data sets.  Functions can be evaluated and plotted.

    The WPlot software comes with an auxiliary program, WFit, which can fit
    a nonlinear function to data and use WPlot to plot the fit.  The WFit
    program was originally written for DOS.  It was compiled as a Windows
    program so that it could use the WPlot program to do the plotting but
    it does not have a true Windows menu interface as does the WPlot program.

    WPlot can be used to plot data collected, calculated, or processed by a
    user written C or Visual Basic program.  The WPlot software now comes
    with a Dynamic Link Library (DLL) containing functions that the user's
    program can call to start WPlot and send plot commands and data to WPlot.

    The WPlot software consists of the following files:

    README.TXT   - This document saved as a text file.
    WPLOT.DOC    - This document saved as a MS Word file.
    SETUP.EXE    - Optional installation program.
    WPLOT32.EXE  - The WPlot plotting program.
    WPLOT32.HLP  - WPlot Help file.
    WFIT.EXE     - Program that finds a nonlinear curve fit.
    *.PLT        - Example plot files that can be loaded by WPlot.
    *.FIT        - Example curve fits that can be loaded by WFit.
    WPLOTC32.DLL - DLL with functions for controlling WPlot.
    WPLOTC32.H   - C header file describing interface to the DLL functions.
    WPLOTC32.LIB - Import library that can be linked with user's C program.
    CMDDEMO.*    - Example C program that controls WPlot.
    VBDEMO.*     - Example Visual Basic program that controls WPlot.
                   NOTE:  VBDEMO.EXE requires Microsoft's MSVBVM50.DLL

    To install the WPlot software on a hard disk, either run the SETUP
    program or follow the instructions described below for manually
    installing the WPlot software:

    NOTE:  If you are installing over an older 16-bit version of WPLOT
    (versions 1.0-2.4) note that the WPLOT executable file is now named
    WPLOT32.EXE rather than WPLOT.EXE and any shortcuts to WPLOT.EXE must
    be modified.

    To manually install the WPlot software on a hard disk, make a directory
    that will contain the software, C:\WPLOT for example.  Then copy to this
    directory all of the WPlot files listed above including the example PLT
    and FIT files.

    To install WPlot and WFit on the Windows 95 Start Menu:

      1.  Click on the Windows 95 Taskbar's "Start" button.
      2.  Select "Settings" and then "Taskbar".
      3.  After the "Taskbar Programs" dialog box appears,
          click on the "Start Menu Programs" tab.
      4.  Click on the "Add" button.
      5.  In the "Command line" edit window type the path to WPlot,
          for example, "C:\WPLOT\WPLOT32.EXE".
      6.  Press "Next" buttons until the installation of WPlot is finished.
      7.  Press the "Add" button again and follow a similar procedure for WFit.
      8.  Finally, press the dialog box's "OK" button.

    To see a demo of the types of plots that WPlot can make, start WPlot
    and select the menu item "File" then "Load Plot Command File" and
    load the file DEMO.PLT.   The file DEMO.PLT and all of the other
    example PLT files must be in the working directory specified above.

    You can also run the demo before installing WPlot on the Windows 95 start
    menu.  Click on the "Start" button on the Windows 95 taskbar then click on
    the "Run" menu item.  Enter the path to WPlot, i.e., C:\WPLOT\WPLOT32.EXE

                      WPLOT SOFTWARE LICENSE AGREEMENT

    The WPlot software is protected by copyright law; it is not public
    domain.  You are granted a limited license to use the WPlot software for
    the purpose of evaluation of the software for a limited period not to
    exceed 30 days.  You are also granted a license to make and distribute
    complete and unmodified copies for the purpose of evaluation of the
    software by others.  Permission is granted to distributors to charge a
    reasonable media and handling fee for diskettes or other media containing
    the WPlot software or for access to the software on bulletin boards or
    FTP sites.  Use of the WPlot software beyond a 30 day evaluation period
    without payment of the $25.00 license fee is a copyright violation.

    Payment of the $25.00 license fee entitles a single user to use the WPlot
    software.  "Single user" means that the software is to be used by only a
    single individual but the software may be installed for that one
    individual's use on multiple PCs (in the individual's office and home for
    example) OR the software may be installed on a single PC and be used by
    multiple individuals as long no two individuals can use the WPlot
    software at the same time.  Installation on multiple PCs or a network
    server with simultaneous access by multiple individuals requires a
    multi-user license.

    The software is provided "AS IS" without warranty of any kind, either
    expressed or implied.
