I use TeeChart to show this diagram. But, when I got the latest version (Version 4.1.2015.3112), I faced with strange bug:
It’s impossible to draw anything before Axis with polar series. I use event “BeforeDrawAxes”, but Axis and series draw after my pictures and hide them.
Like in this figure:

If I draw my figures and circles in method “AfterDraw”, my picture hides all grids and series.

So I have to use transparency to get the chart slight alike what I need.

How you see, this is not readable.

What can I do to get the chart like it was with previous versions?
For example (version 4.1.2011.7283):

In order to prove my words I made two solutions (small applications):

Many thanks.

Apologies for this small regression. You can recuperate the previous behaviour with a one-line modification:

Code: Select all

    private void Form1_Shown(object sender, EventArgs e)
    {
      int ScaleCount = 8;
      var r = new Random(1);
      for (int i = 0; i < ScaleCount; i++)
      {
        var CSValue = r.Next(3, 9);
        polar1.Add((double)-i * 360 / ScaleCount, CSValue);
      }

      polar1.CircleBackColor = Color.Transparent; //<- new line
    }

Again, apologies for any inconvenience caused.
