Hi Simon,
The "stats" TPaveText object is created when the histogram is drawn.
If you execute a macro, you must force an Update of the canvas to get
the histogram drawn. The Draw function simply adds the histogram to the
list
of objects to be drawn when the canvas is updated.
Here is a small macro illustrating how to operate.
{
hpx->Draw();
gPad->Update();
TPaveText *stats = (TPaveText*)gPad->GetPrimitive("stats");
stats->SetTextSize(0.02);
gPad->Modified();
}
