I have two questions. I couldn't find its answer.

1.  I have plotted a contour plot by TF2. I want to
change the number/position of grid lines. I tried with

gr->GetXaxis()->SetNdivisions(80 + 100*4);

It works for 1-d TGraph. But it did not work for

2.  In the above contour plot, I want to print the
values of the function (which corresponds to different
lines) on the plot.                                 

Could you please suggest me how to do this.

Thank you very much.
