3D histograms with BOX/LEGO

PascalXie · December 2, 2014, 1:40pm

Hi,
I use ROOT to make a 3D histogram with the option “LEGO”. And I get a 3D figure in which each box is just frames. There is no faces or the faces are totally transparent.
I was wondering can I make a 3D histogram in the option “LEGO” with boxes whose faces are non-transparent?

Try the option “GLBOX”

Thank you for the response.
After the option “GLBOX” used, the 3D histogram is not changed and ROOT replied that “Error in TGLHistPainter::DistancetoPrimitive: Attempt to use TGLHistPainter, while the current pad (gPad) does not support gl”.
Is there something wrong with the gPad that I use?

before do:

gStyle->SetCanvasPreferGL(kTRUE);
