Hi Gareth, I'm no expert on such matters but through experimentation I have found that IJPEGExport.CompressionQuality certainly affects the quality of the image (and of course the file size), but does not affect the resolution (dpi) as reported by imaging applications, which always remains at 200dpi...

Hi -- Rather than using: if isnull(rst("min")) or rst("min")=0 then chart.series(0).addnull rst("date") else Chart.Series(0).Add rst("min"), rst("date"),RGB(34,150,123) have you tried using: if isnull(rst("min")) or rst("min")=0 then chart.series(0).addnullXY rst("date"), 0, "" else Chart.Series(0)....

Hi -- Even 2 seconds seems a bit slow doesn't it? Well, I'm sure this figure would be lower on a more up-to-date machine. Is there some way to stop the update of the screen until after an operation is completed (ie. after the window has been moved, etc)? Mmmm, you might want to experiment with the S...

Hi -
Could you try the following:
Sure. On my desktop (Pentium 4 1700 running Windows v5.2.3790) the repaint of TeeChart for .NET v1.0.1189.31308 takes just under 2 seconds for 150.000 points.

Hi --
Is there a way to alter the resolution of the output stream when exporting as JPG or GIF?
Is not IJPEGExport.CompressionQuality what you're looking for?

Hi --
Do you have any other suggestions?
How about using a FastLine series and:
fastlineSeries1.DrawAllPoints = false ;

as in the example in the Features Demo under:
All Features -> Welcome! -> Speed -> Fastline Speed DrawAll.

For example, if I create a full node structure and then I realize that the whole thing should've been created under a different root, I don't seem to be able to move the whole tree portion to the new root... I think that some left, right, up, down ar...
