[ROOT] hist drawing question (fwd)

Hi rooters,

I am using root version 2.26/00.

I have a normal TH1F hist hctaudis. I created another one
hct by calculate some function and then I do

hct->SetBinContent(i,xx);

for each bin. xx is a float. At last I also did

hct->SetEntries(number);

Now I want to overlay the two hist in one plot when
y axis is in log mode(in linear mode it works)

If I do

hctaudis->Draw();
hct->Draw("Csame");

it is fine.

If I do

hctaudis->Draw("e1p");
hct->Draw("Csame");

hct will never show up.

Does any one can help me out this problem?

Thanks,

Hongquan
