Grid in log-scale figures

  Hello!

  Is there a way to precisely state which grid lines are drawn when
using log-scale figures? Depending on the number of ticks, Matlab
plots grid lines between two tick marks or not.

  E.g., using the following code on my 800x600 resolution Win NT-PC,
ML 6.0 plots grid lines between the powers of 10 (indicating [1e0 2e0
3e0 ... 8e5 9e5 1e6]) :

figure;
set(gca,'XScale','log','XLim',[1e0 1e6],'XGrid','on');
set(gca,'XTick',[1e0 1e1 1e2 1e3 1e4 1e5 1e6]);

  However, using

set(gca,'xtick',[1e0 1e2 1e3 1e4 1e5]);

just draws grid lines where I want them to be (i.e. at the powers of
10).

  Any guess how to switch off the additional grid lines in the first
case?

  
  Happy Matlabing,

    Rene'
