Besides having a problem with labels on major tickmarks on X axis
in the following macro, I cannot force these labels any closer to the
X axis with gStyle -> SetLabelOffset(0.00001, "X") than some default
value, which is about 0.1 of pad height.

gROOT -> Reset();
TCanvas *cc1 = new TCanvas("cc1", "My Canvas", 600, 800);
gStyle -> SetTitleX(0.22);
gStyle -> SetTitleY(0.97);
gStyle -> SetLabelOffset(0.0001 "X");
gPad -> SetBottomMargin(0.15);
gPad -> SetLeftMargin(0.15);
gPad -> SetTicks();
gPad -> SetLogx();
gPad -> SetLogy();
