Log scale in Pad when pad number is a variable

ROOT

The situation is the following: A Canvas is divided in several pads,
a loop is running over the pads and drawing the appropriate histograms in
the respective pads:
for (int iPad=1; iPad<=4; iPad++)
{
OutPlot[iCanv]->cd(iPad);
int histo=4*(iCanv)+iPad-1; // a 2x2 divided canvas
if (lLogy[histo]) …
if (histo<nhist) myHist[histo]->Draw();
}

at the … the pad should be switched to log y. How do I specify the pad number, if it is a variable? OutPlot[iCanv]_iPad-SetLogY();
does obviously not work. Thanks in advance for comments.
