DPlot

Hi David!

Yes, the problem is due to incorrect command which I send to DPlot_Plot.

I'm using Intel Fortran. I declare NULL_PTR as and pass it to DPlot_Plot. After that everything work fine.

Thank you for you help!

If use first DPlot_plot without command DocMaximize DplotJr behave very strange.
1. It don't show any curves only axis and grid lines, but when switch grid lines or/and box options the curves appear.
2. AddData don't add any data and return undocumented error code: -16393

If use DocMaximize ...

If you would rather the plot be resized then don't use ManualScale before calling DPlot_AddData.

I want the plot window remain the same size and the same position.

Or instead of DPlot_AddData you could repeat the call to DPlot_Plot.

But DPlot_Plot create new Document, isn't it?

Yes, it's my fault!
But still, I think, DPlot show strange behaviour.
1. Why it check for exact equivalence of float number? I think it was more naturally to consider two float is equivalent if they are in some epsilon vicinity.
2. Why instead of resizing of the plot window it shift it?
3. And why ...

Now I am trying to use DPlotJr with Intel Fortran.
Example from \dplotlib\fctest compiled and work with Intel Fortran

I am trying to make some animation with DPlotJr on Fortran.
I have wrote next example:

! Filling arrays x and y
DPlot.Version = DPLOT_DDE_VERSION
DPlot.hwnd = 0;
DPlot.DataFormat = DATA_XYXY
DPlot.MaxCurves = 1
DPlot.MaxPoints = NP
DPlot.NumCurves = 1
DPlot.Scale = SCALE_LINEARX_LINEARY ...
