ChartRect not updated ?

[Verane]

Hi,

I am using Tchart in my application (version of my TeeChart.dll is 1.1.1769.19457).
I have some unit tests written with NUnitForms that perform tests on my application.
From my tests, I have a problem with the chartRect of a chart not updated. When I get this chartRect from my code, I always get (0,0,0,0); but sometimes, just by looking at the chartRect value in the Visual Studio debugger, my chartRect value is updated and then my test pass.

I don't understand why looking at the chartRect property in the debugger updates its value... And how can I have directly the right value in chartRect ?

Here is my code:

ChartTester chartTester = new ChartTester("RawData1DChromatogramOffLine0"); //NUnitForms tester for TChart

Steema.TeeChart.TChart theChart = chartTester.Properties;
Rectangle rect = theChart.Chart.ChartRect; //wrong value in rect, but can be updated when addingTheChart.Chart in the visual studio debbugger "watch" window.


Thanks,
Verane.

Hi Verane,

The ChartRect is not calculated until the whole chart is drawn as many things need to be drawn first (i.e.: axes). To force the chart being drawn you can make a call to tChart1.Bitmap.
