Performance Issue

Post by X-ray » Thu Jul 10, 2025 1:23 pm

Hello,

We have some performance problems drawing large TColorGridSeries of sparse matrices, see attached plot. Basically, there is only the small diagonal patch in the middle where there is data to plot:

The area of the Red Triangles is empty and doesn’t contain any data. Is there a way to speed up handling and drawing by telling the plot that there are parts of the data that don’t need to be plotted?

Thanks and best regards,
Thomas
