Hi Tuan Nguyen,

You could try using Polar series for that. You'll find some examples at All Features\Welcome!\Chart Styles\Extended\Polar in the features demo, which can be found at TeeChart's program group.

Hi Tuan Nguyen,

Using Polar series, negative labels will be plotted if you used negative data. Another option would be that you use SetMinMax method for manually setting each axis minimum and maximum values.

Regarding drawing additional circles, you can do it as shown in the All Features\Welcome!\Chart Styles\Extended\Polar\Zones example at the features demo.

Another option to plot the kind of chart you request is using what we suggested here. For drawing the additional circles you should custom draw on TeeChart's canvas as shown in Tutorial 13 - Custom drawing on the Chart Panel. You'll find the tutorials at TeeChart's program group.
