Grid Lines on Primary and Secondary Tick Divsions

I am trying to make a plot in ROOT with grid lines. I can make them appear on the primary tick marks but not on the secondary ticks. Here’s a sample macro…

[code]{
TCanvas *c1 = new TCanvas;
TH2I *h2 = new TH2I(“h2”,“title”,10,0,10,10,0,10);

for(Int_t loop = 0; loop <10>Fill(loop,loop);
}

c1->SetGrid();
gStyle->SetGridStyle(0);
h2->GetXaxis()->SetNdivisions(-205);
h2->GetYaxis()->SetNdivisions(-205);
h2->Draw(“text”);
}[/code]

Any ideas about getting the grid to appear on the secondary ticks?

Grid is drawn on primary tick marks only. If you need more grid lines, increase the number of primary divisions.
