  • Rhea-PV2D (Plotting software)

    Rhea-PV2D is an easy-to-use rapid 2D plotting tool. PV2D stands for PlotView-2D and is a complimentary tool to Rhea-Emulus (digitizer) and Hyperion-CADRazor (3D OpenGL tool). PV2D has been updated to support native PLT file formats and free text formats. The user can simply drag data files into PV2D. Rapid zoom changes can be accommodated by the mouse wheel and left-mouse selections. Data statistics can be processed with a selection window as well, providing controlled MIN/MAX, integration and averaging of selected points in the window. Finally a developers edition is available where PV2D is compiled to a DLL, giving parent applications exceptional plotting capability with a simple API call structure. Simply send the data file name to PV2D.dll and call a refresh.

    By request, I have included a demonstration of the PV2D.dll developers version. You can download the following zip file:

    Unzip this into a directory and compile the demo file (PB .bas file). The directory contains the PV2D.dll module and also includes a sample plot file which is sent to the DLL. At the moment, data handling is done across fixed files but it would not be difficult to hand off data in memory similar to the CADRazor and OV3D.dll modules.

    Feel free to contact me if you have any questions. There are email addresses on the contact page as well.
