WPF. SubChart. Performance problems.

Post by neurosoft » Mon Aug 18, 2014 10:55 am

Hello steema!
I have terrible performance problems with the latest version of WPF TChart if I use SubChart.
Try to execute the following code and resize window with TChart to reproduce that:

Code: Select all
SubChartTool subChartTool = new SubChartTool();
MyTChart.Tools.Add(subChartTool);
TChart subChart = subChartTool.Charts.AddChart(string.Empty);


TChart must be resizable.
It seems that TChart.OnRender is called recursively.

It's awful bug, fix it ASAP please.

Hello neurosoft,

I am afraid I can't reproduce the problem here. Could you please send us a simple code where we can reproduce the problem here?

Thanks in advance,

Ok. I've attached a simple example where the problem appears. Just add to the project a reference to the latest version of TeeChart.WPF, run application and press the button 'button'. Then application works very slowly and processor is busy too much.
