Hello, I did a modification to try to fix this problem: https://www.steema.com/support/viewtopic.php?f=3&t=16643 However, precisely today I found that fix broke the TDonutSeries drawing when using GDI and 2D. The Donut function I modified assumes StartAngle and EndAngle are already in radians. To fi...

Hello,

Find here the sources of the TeeNew project:

Hello,

You probably need to force a chart repaint so some internal properties are calculated the second time the OnGetLegendRect event is fired.

Hello,

You should calculate the Line Interpolation as shown in the example here.

Hello, Excuse us for the delayed reply here. I want to shade a quadrilateral area of the TChart panel to indicate a certain range of validity of plotted values. I'm not sure of the best way to do this. I found that I can draw a polygon using TeCanvas.TCanvas3D.Polygon, and I have put that in the cha...

Hello,

What Visual Studio version are you using?
Could you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Hello, This happens because the CustomAxes don't "inflate" the chartRect like the default axes. You can workaround this setting some extra margin. Ie: procedure TForm1.CheckBox1Click(Sender: TObject); begin Chart1.Axes.Left.Visible:=CheckBox1.Checked; if Chart1.Axes.Left.Visible then Chart1.MarginLe...

Hello, I've just fixed the issue. Since you own the sources, you can apply the fix to your sources. At CustomBar.java, change the drawLegendShape method for this one: protected void drawLegendShape(IGraphics3D g, int valueIndex, Rectangle rect) { ChartPen oldPen = g.getPen(); if (getBrush().getImage...

Hello,

I could reproduce it so I've added it to the public tracker:

Hello Neil, The only thing I can think in that %user% path that could be interfering when building the TQRChart packages is the "Projects" folder. Maybe that folder was present in your library path and it may contain TeeChart compiled units that were found before finding the sources. Anyway, I'm gla...

Hello, I'll test the packages Marc attached with the TeeChart Standard (Commercial) v2018.26 and I'll post the results here. The precompiled packages from here seem to work without problems for me. I just copied the DclTee9QR506D26.bpl package from the compiledwin32 folder into the "bin" folder in t...

Hello Neil,

Hello, I've added it to the public tracker. http://bugs.teechart.net/show_bug.cgi?id=2135 Also, I'll merge this thread into the initial one. A workaround could be to set "GDI+" as "Render" at the "New Chart" tab in the design time "Options", and then set the Chart to use GDI: Chart1.Canvas:=TTeeCanv...

Hello Mark,

I've added it to the public tracker:
http://bugs.teechart.net/show_bug.cgi?id=2133

Hello, I see in your Call Stack the TTeeCanvas.DoChangedFont method is being called while in the example I run here it calls the TGDIPlusCanvas.DoChangedFont method. So the difference seems to be in the Render option being used GDI vs GDIPlus. If I change the Render in the "Options\New Chart" to "GD...
