I am using a TColorGridSeries to display images. When I put 500,000+ points in the series, it redraws EXTREMELY slow (for example, when the chart is resized, zoomed or a repaint is issued). I tried setting BufferedDisplay to false and this didn't really help.

Is there anything I can do to speed this up? I desperately need to speed this up...any suggestions?

Thanks.

I have been talking offline with Narcís on the TColorGridSeries speed issue while the forums were down.

The slow speed is very obvious regardless of the number of points when IrregularGrid is set True. As you would expect, the more the points, the slower the plot.

In the end, Narcís says that there is nothing that can be done to speed up the plot. Regardless of the hardware you are using, the plot is incredibly slow. Everyone will agree, this makes the plot unusable.

If anyone else has noticed this and has a work around, please post a response as soon as possible. It is a shame to go find a different package since up until now, this one was so nice.

Also, if others have used other packages with Delphi that they have experiences with, please send comments to [email protected]

Thanks
