Re: Pie chart Export as HTML5 Canvas

Hello, I see the marks at the correct positions. What TeeChart VCL version are you using? What the link to the teechart.js at the header of the generated html page? I see the Pie slices are drawn anticlockwise in VCL and clockwise in JavaScript. I've added it to the public tracker: http://bugs.teech...

The FastLine series in TeeChart.NET should be translated as Tee.Line series in TeeChart Javascript.
This was implemented the 21/11/2018. So you should use a TeeChart .NET version released after that date to correctly export FastLine series from .NET to Javascript.

Re: How to best draw (custom) legend with used Pointers

Hello, Drawing legend items in 3D as the series using OpenGL is not so easy because all the objects are drawn following the view (rotation and elevation) except for the default legend, where we disable the 3D to draw it as a plane. This means you can't use the Legend.Symbols.OnDraw event to draw 3D ...

Re: How to best draw (custom) legend with used Pointers

Hello,

The easier would probably be to hide all your series from the legend (ShowInLegend:=False) and then create as many new series as pointers+text you want to show in the legend. These new series won't have any value but you can set them your pointers and titles to show them in the legend.

Re: Configuring marks (in a pie series)

Hello, I can decrease the font size a bit, but how do I hide the background (via code please). You can call "Marks.Brush.Clear". Can I decrease the pie size a little? You can manually set a CustomXRadius. Since the Cirlced property is set to true by default, you don't need to set the CustomYRadius. ...
