how can I tell when a Repaint has finished?

[Andrew]

I have a chart which I'm populating like this:

Code: Select all

Chart->AutoRepaint = false;
for (many thousands of values)
{
    lineseries->AddXY(x,y,"",clRed);
}
Chart->AutoRepaint = true;
Chart->Repaint();

The problem is that the Repaint does not happen immediately. If I call Repaint(), and then immediatelly check the XValues or YValues lists for my series, they are empty. I need to know when the data is actually visible on the screen (and the X/Y lists have been populated), which doesn't happen until ? milliseconds after the Repaint is called. Is there some sort of property I can check, or method I can call to see if a Chart is still repainting? Any suggestions as to how I can tell that all data is now shown on the screen?

Cheers,

Andrew

Hi Andrew,

You could use TChart's OnAfterDraw event for that purpose. An alternative could be using Series' OnAfterDrawValues.
