Hello, Transparency is applied with Blending: uses TeCanvas; //... var tmpBlend : TTeeBlend; const transp=80; begin //Prepare Pen and Brush if transp>0 then tmpBlend:=Chart1.Canvas.BeginBlending(TeeZeroRect,transp); //Draw polygon if transp>0 then Chart1.Canvas.EndBlending(tmpBlend);

Great! Thanks for the feedback.

Hello,

Right. I've added it to the public tracker (#2369)

Hello,

No I can't reproduce it. Could you please arrange a simple example project we can run as-is here?
Thanks in advance.

Hello, You could check if the left axis title fits in the chart height and wrap the text accordingly.

Hello, Is there a better way to mark Axis Labels as closely as possible? Except, LabelsSeparation := 1. I'm afraid the only alternative would be to manually populate the labels yourself. Ie: var lHeight: Integer; curVal: Double; dif: Double; begin Chart1.AddSeries(TPointSeries).FillSampleValues(10);...

Hello, In the AddArrays example here , we populate arrays in a similar way than what you are doing. So it looks good to me. - .h: class CVCTeeChart5Dlg : public CDialog { public: //... COleSafeArray XValues; COleSafeArray YValues; //... - .cpp: BOOL CVCTeeChart5Dlg::OnInitDialog() { //... DWORD numE...
