DPlot Jr

DPlot Jr is a free scaled-down version of DPlot intended for use by programmers who want a quick method for displaying graphical output of their own applications. Unlike the full version of DPlot, DPlot Jr may be redistributed to end users without royalty payments or other restrictions. There's nothing to buy and no registration fee involved. DPlot Jr is not intended to be a standalone graphing program. Input to DPlot Jr is accomplished through Dynamic Data Exchange (DDE), either from your application or via the supplied DPLOTLIB interface. The end user cannot open a file or paste data from the clipboard. DPlot Jr also lacks many of the editing and data generation features of the full version.

DPlot Jr is distributed with several demo programs illustrating, among other things, how to send data to DPlot Jr and automatically produce a plot. Source examples for Microsoft C, C#, Borland C++, LCC-WIN32, GNU C (gcc), Microsoft Visual Basic, Visual Basic .NET, PowerBasic, FreeBASIC, Absoft FORTRAN, Compaq Visual FORTRAN, GNU FORTRAN, Salford FORTRAN, and WATCOM FORTRAN are included in the distribution. (HTBasic users: Check out Graph-XT, an HTBasic library from Tech Soft GmbH making use of DPlot and DPLOTLIB.DLL.) Shown below are several examples from the demo programs included with DPlot Jr.
