[ROOT] marker when a tree is drawn

Hi,

    I am having a problem to set the marker size and style when I draw directly from a tree:

        myTree->Draw("var1:var2",cut);

    If I try to set the marker attributes for the histogram "htemp" there is no effect. The same happens
if I try to do it interactively with the mouse.

    When I first book a TH2F histogram (named "histo") and then I do:

        myTree->Draw("var1:var2>>histo",cut);

then I can set the marker attributes for the histogram "histo".

    Any way to do it directly on the first case without booking a histogram?

    Thanks!

Stelios.
