graphics.DrawLine

PrTester · 03-17-2009, 09:31 AM

Probably this is beyond the support but if any advance user can help would be appreciated.

I want to plot a few lines with the graphics.DrawLine method inside the public override void Plot(), I don't know the qty of the lines to be plotted and every time I plot a new line, the old one disappears. Any ideas?

Regards

This is unfortunately outside the scope of what we can support. Maybe if you take a look at the Pivots indicator code you can get some ideas from there.

That is the way it works. You need to draw all your graphics with every invocation of plot(). The other way around, there is no need to delete any obsolete objects.
