Hi, I attached an image of chart I would like to create. There are 8 signals and each has it's own left axis. All 8 signals and axes are on the same chart. Is it possible to do that with teechart? I tried to add axes and move them by changing position properties but the end result was quite bad. Can...

Thanks!

Hi,

I derived my custom series from TCustomSeries and whenever I go with mouse over series on chart I get hint with some value. I would like to disable those hover hints. How can I disable those hints?

Thank you in advance.

Hi, thanks. I checked out several things, including my BitDefender antivir sw. It reports that TeeCompile might be potentionally dangerous. bitdefender.png Anyways I put TeeCompile on my whitelist and now it seems fine. Next thing I checked was folders System32 and SysWOW64 and you was right. There ...

Hi, I downloaded and installed it in Delphi XE6 and XE8. I (still) have problems with loading packages in Delphi XE8 (Delphi XE6 has no problems - loading packages went perfectly) 1. I ran TeeCompile.exe and checked Delphi XE6 and XE8. Installation went just fine. Here are settings 1.png and my fold...

My bad. I didn't pay attention to it. Thanks.

Hi, I have TeeChart 2015 with sources and Delphi XE8. For the first time ever I am experiencing problems with TeeChart component installation.

Currently I am handling onMouseMove event and when I detect point is in the rectangle I try to set Chart.Curs...

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 :...

Is there any performance difference in calling chart.Repaint or Chart.Invalidate? What is the difference between them chart implementation wise?

Thanks

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.

Hi, I am doing some custom drawing on my chart control in connection with mouse movements. In other words, whenever I move mouse I am drawing some graphics on my chart. Right now I am handling chart's OnBeforeDrawSeries and OnMouseMove. eg. (just an example to show my apporach): procedure xxx.OnMous...

Thank you again.

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...

Thank you for clarifying.
