I got a TH2F histogram, each bin of that represents energy in one cell in the detector. Is there a way to draw borders between bins to make a more clear distinction between them?
I know about TLine, but is seems quite unsuitable here to use it.
I do not think that such option exists, but @couet can correct me
It is not foreseen as an option. But it is simple to do:
double xs = 0.2; // grid step along X
double ys = 0.2; // grid step along Y
auto aline = new TLine();
for (double yg = ymin+ys; yg < ymax; yg=yg+ys) aline->PaintLine(xmin,yg,xmax,yg);
for (double xg = xmin+xs; xg < xmax; xg=xg+xs) aline->PaintLine(xg,ymin,xg,ymax);
auto h = new TH2D("h","",10,0,10,10,0,10);
auto grid = new TExec("grid","drawgrid()");
