Re: How to calculate Y from X value (LineSeries with Smoothing)
This is rather old post but I think it's still interesting problem. Here is the code of base interpolation algorithm: function InterpolateSeries(Series: TCustomMultiSeries; XValue: Double; var DataIdx: Integer): Double; var Index: Integer; dx, dy: Double; FirstIdx, LastIdx: Integer; begin FirstIdx :...

Re: Chart custom graphics drawing
Is there any performance difference in calling chart.Repaint or Chart.Invalidate? What is the difference between them chart implementation wise?
Thanks
Thanks

Re: Chart custom graphics drawing
Yeah sure. I totaly forgot that all series are repainted too. I have up to 16 series with up to 4000 samples. So although my custom drawing is super fast it will always take some time to paint all 16 series. It makes sense.
Thanks for the hint and test of my code.

TColorBandTool limits
Hi, I am using TColorBandTool as a special data selector on my chart. It looks like a resizable yellow rectangle (start and end lines are allowed to be dragged). That rectangle can be any size now ( depends upon values StartValue, EndValue) but I would like to limit that. My question is if it's poss...
