is it possible to use TGraphPainter::Smooth() to get the interpolated values?
For instance, lets have an initializes and filled TGraphErrors *g, I would like to do the following:
Double_t ax, ay;
TGraphPainter *gp = new TGraphPainter();
But then when I check the values of the ax and ay arrays, they are all empty:
for (int i=0; i<10; i++) cout << ax[i*50] << " " << ay[i*50] << endl;
Am I doing something wrong or is it not possible to do this way? I know there is TGraph::Eval() but looking at the code of TGraphPainter it seems to me the above way should work too.
