Re-labeling an axis

[Laura Fowler]

I am trying to re-label the x-axis but this is not working well. By default,
the x-axis is labeled with the labels 0 to 0.02E with a 0.002 increment. I
have 200 grid-points along the x-axis.

Using "set xaxis 0. 0.020 0.004', I am able to reduce the number of labels
which is what I wanted to do first.

What do I need to do to re-label the x-axis (0 0.004E 0.008E 0.012E 0.016E
0.020E) to (0 40E 80E 120E 160E 200E)?

I tried xlabs and I tried xlevs, but my labels appear crunched together on
the left side of the xaxis.

I must be missing something. Can you help?

Thanks.
Laura
