Hi,

You need to adjust the Major Unit of the Value axis.
In xl2003 you can use the Legend to do this. Format legend and on the Scale
tab adjust Major Unit.

In xl2007 you will need to select the value axis.

Cheers
Andy

I have data that needs to be plotted in a surface contour plot. The Z axis
is in percentage of the maximum value. The plot will only show the curves
in
20% increments. I would like at least 10% resolution, better yet 5%. Is
there any way to change how the plot is drawn to get these resolutions?
