A Problem about Polar Chart with Logarithmic Coordinates

Post by Gobing » Tue Sep 01, 2009 5:24 pm

Dear Sir:
In the TeeChart control added to my project, I added a ‘Polar’ series, then labeled the top, bottom, right and left axes with logarithmic coordinates by writing the follow codes:
m_TeeChart.GetAxis().GetLeft().SetAutomatic(FALSE);
m_TeeChart.GetAxis().GetLeft().SetLogarithmic(TRUE);
m_TeeChart.GetAxis().GetLeft().SetMinMax(1, 100);
m_TeeChart.GetAxis().GetLeft().SetIncrement(10);

m_TeeChart.GetAxis().GetRight().SetAutomatic(FALSE);
m_TeeChart.GetAxis().GetRight().SetLogarithmic(TRUE);
m_TeeChart.GetAxis().GetRight().SetMinMax(1, 100);
m_TeeChart.GetAxis().GetRight().SetIncrement(10);

m_TeeChart.GetAxis().GetTop().SetAutomatic(FALSE);
m_TeeChart.GetAxis().GetTop().SetLogarithmic(TRUE);
m_TeeChart.GetAxis().GetTop().SetMinMax(1, 100);
m_TeeChart.GetAxis().GetTop().SetIncrement(10);

m_TeeChart.GetAxis().GetBottom().SetAutomatic(FALSE);
m_TeeChart.GetAxis().GetBottom().SetLogarithmic(TRUE);
m_TeeChart.GetAxis().GetBottom().SetMinMax(1, 100);
m_TeeChart.GetAxis().GetBottom().SetIncrement(10);

We would see all labels beside four axes became logarithmic format. Unfortunately those circular grid lines were still drawn on the polar chart with the same interval between each other, not following these logarithmic labels. So I doubted whether I did not set some properties correctly or some bugs? I hope you could help me find out the reason. Thank you in advance.

Hi Gobing,

Yes, it seems that having a Polar series with logarithmic axes, the labels overlap. I've added it to the wish list to be fixed in future releases (TV52014379).

I am sorry, sir. Maybe I didn't express my means clearly. I didn't care about the overlaped lables . I means that, the circular grid lines weren't drawed according to logarithmic labels on the polar chart.

Hi Gobing,

Thanks for the information. I understood and could reproduce your problem here now. I've added the defect to the bug list (TV52014380) to be fixed for future releases.
