Hi,
If you format the value axis you should see an option to apply Log scale.
in xl2003 it's on the Scale Tab of the Format axis dialog.
in xl2007 it on the Axis Options section of the Format axis dialog,
Cheers
Andy

I know how to create a regular line graph, but don't know how to create a
logarithmic chart.
