This issue is still reproducible, it is actually about the Transparency property returning 0 when called first time and 100 when called second time. The same happens to many chart types and elements that have Transparency property.
Run the below snippet and see the value of the 2nd message box.
Donut donut = new Donut();
tChart1.Series.Add(donut);
donut.Add(2d);
donut.Add(3d);
donut.Add(new double?()); //add null
//check the transparency value, first time, it will be 0
MessageBox.Show(string.Format("Transparency is correct: {0}", donut.Transparency));
//check the transparency value again, it will be now 100
MessageBox.Show(string.Format("Transparency is wrong: {0}", donut.Transparency));

Hello Sunil, The problem you're experiencing is fixed for latest TeeChartFor.net 4.1.2017.10190 Thanks in advance |
TeeChart v4.1.2017.03140 For most of the chart types Donut, Pie and others, adding null value will reset the transparency to 100. Donut donut = new Donut(); tChart1.Series.Add(donut); donut.Add(2d); donut.Add(3d); //check the transparency value, it will be 0; MessageBox.Show(donut.Transparency.ToString()); //add nullable donut.Add(new double?()); //check the transparency value, it will be 0; MessageBox.Show(donut.Transparency.ToString()); //check the transparency value again, it will be now 100; MessageBox.Show(donut.Transparency.ToString()); Also, when some properties under wall/aspect is changed, it will reset the series.Transparency to 100, making the series invisible.
