+<li> In <tt>THistPainter::PaintAxis</tt> repainting (<tt>gPad->RedrawAxis()</tt>)
+ alphanumeric labels axis on a plot done with the option HBAR (horizontal)
+ needed some adjustements. The following macro showed the problem. The
+ axis labels were wrongly painted:
+<pre>
+ {
+ TCanvas* canvas = new TCanvas("Canvas", "Canvas", 0, 0, 1000, 500);
+ canvas->Divide(2,1);
+ THStack* stack = new THStack("Stack", "StackTitle");
+ TH1F* hist1 = new TH1F("Hist1", "Title1", 1, 0, 100);
+ TH1F* hist2 = new TH1F("Hist2", "Title2", 1, 0, 100);
+ hist1->SetFillColor(kBlack);
+ hist2->SetFillColor(kGray);
+ for (int i = 0; i < 4; ++i) {
+ char dataName[50];
+ sprintf(dataName, "Data%d", i);
+ hist1->Fill(dataName, 10 + 50*i);
+ hist2->Fill(dataName, 145 - 40*i);
+ }
+ stack->Add(hist1);
+ stack->Add(hist2);
+ canvas->cd(1); stack->Draw("nostack,bar");
+ canvas->cd(2); stack->Draw("nostack,hbar");
+ }
