Re: how can I change background color of a chart?

Hello,

You can set the back wall. Ie:

Code: Select all

  Chart1.walls.back.format.gradient.visible=false;
  Chart1.walls.back.format.fill="gray";

Re: Android - Memory increase - Repaint

Hello, I got a "out of memory" exception in my Project after 40 minutes. I check the memory in Android with the standard memory usage display in settings. I've been able to see the memory leak in the system configuration, as you suggested, but I'm afraid haven't been able to find the cause of it so ...

Re: General question about antialias drawing

Hello,

I've just rebuilt the test program from that thread with the current v2018.26 and I can see a difference between "GDI+" and "GDI+, AndtiAlias only in Series" modes:

Re: Point series and marks text position

Indeed the ArrowLength is only applied when YMandatory is true: Procedure TCustomSeries.DrawMark( ValueIndex:Integer; Const St:String; APosition:TSeriesMarkPosition); //... if YMandatory then Marks.ApplyArrowLength(APosition); //... This was probably made to avoid problems. I see it's like this sinc...

Hello,

How are you monitoring the memory consumption?
Please arrange a simple example project we can run as-is to reproduce the problem here.

Re: Drawing big plots

Hello,

I'm not sure if this is possible.
There seems to be quite a consensus in advising against it.

But you could give a try at the techniques described here and there.

Re: Problems with ChartTool1GetText

Hello,

There must be some difference somewhere. If you can't find it in your application you may try to extract the minimum parts from it to reproduce it, slowly converting it to the test I posted above. At some point you should be able to notice the difference.

Re: Drawing big plots

Hello,

I'm afraid TeeChart isn't thread-safe and updating visual controls from outside the main thread is not advisable as can be read here.
