Hi.

I want to plot a frequency (measured in Hz, x-axis) :
level (measured in dBfs, y-axis) chart in Excel (2000) -
I'm importing data from a .txt file which I have to got
work fine, with the data appearing in the spreadsheet.

My problem is that I want to create a logarithmic scale on
the x-axis but not to the base of 10 (default). At every
set interval/distance on the x-axis I need the value to
double (i.e. starting from 20Hz, then 40, 80, 160, etc.).

Is there any possible way of doing this?

Thanks for your help.
