Please note: Licensed users who are not currently using version 1.8.2 of DPlot will need to download and install the latest registered version before installing any of these new beta releases. If you are a licensed user and are not signed up for the mailing list, contact me for the details on obtaining version 1.8.2.
Changes to DPLOTLIB:
- DPlot_SetErrorMethod allows you to specify how error messages are reported. Default is via OutputDebugString; you can change this to no error messages or MessageBox. In general DPLOTLIB now does a better job of reporting error conditions. This function should be particularly useful to programmers using an environment not specifically mentioned in the DPLOTLIB documentation.
- DPlot_GetBitmapEx is identical to DPlot_GetBitmap, but additionally returns plot metric information so that the calling program can convert bitmap pixel coordinates to plot space. This can be used, for example, to display X,Y coordinates of the mouse position as the user moves his cursor across the bitmap. The updated btest2 example illustrates this feature. Thanks to Chris Rouleau for the suggestion.
- DPlot_AddData allows you to add data points to an existing curve and/or create a new curve in an existing document. The new btest3 and ctest3 examples use DPlot_AddData in a real-time simulation.
- Real-time simulations in C and Visual Basic have been added to the DPLOTLIB distribution. See btest3 and ctest3 examples.
- Removed the "Use arrow keys to pan" message from the status bar when zooming. This message was previously locked in for 5 seconds and was an annoyance for many users.
