Re: ISO CHARTS

Hello,

Where you refer to ISO AXES I assume you've seen this demo:

https://github.com/Steema/TeeChart-VCL- ... metric.pas

It is designed to set the increments equally across x and y axes. Is that now what you have in mind?

With thanks.
Regards,

Please check that there are no folders left over from the previous install that may include teecalc.exe and that you are running the new installer with administrator rights.

I would like to have the Zero Value at 12 o’ clock position and increments in clockwise direction. You can set the "Rotated" property (in the Circled tab of the Series in the ...

Re: Keeping the Legend Symbols the same size

Hello Ed,

Code: Select all

This concerns me about FMX though--no one here.
Yes, we were slow to react to your post. Workload doesn't always allow us to get to every post straight away; we should have noticed your post on the TeeGrid forum and moved it to TeeChart.

Re: TContourSeries: slowing down problem

Hello Friedrich, Yes, the https://www.steema.com/support/viewtopic.php?f=4&t=3316 was an interesting discussion. Though many of the issues are somewhat different for Delphi, which is unmanaged and much faster by nature, it merits a deeper look. Your point about DrawAll could be worth investigation t...

Re: Misssing TChart.Panel

Hello, I'm not familiar with the use of TChart.Panel; There are classes that have a similar name, such as TCustomTeePanel or TCustomTeePanelExtended; These are declared in TeeProcs (that is normally a default 'uses' in the forms of a project using TeeChart). We'll need to see more specific details o...

Re: Fixed x to y ratio

Hello Errol, Check that your chart has had at least one proper repaint before running the method. For example, if I check this value, Series1.GetVertAxis.ParentChart.ChartHeight, in Form Create before the first paint, ChartHeight/Width return 0. If you run the code from the demo itself you may find ...

Re: TBarSeries - Problems on accessing BarChart Marks

Hello,

You need to set:

Code: Select all

  chart1.Series[0].Marks.AutoPosition := False;
  chart1.Series[1].Marks.AutoPosition := False;
otherwise TeeChart will not create/render Marks at locations that are obscured by others.
