How do I show contours on a log scale?

[Gareth]

G'day,

In making a contour plot I have contours varying by orders of magnitude. So, displaying them on a linear scale is an issue.

Is it possible to display the contours on a log scale?

Any help would be much appreciated

You don't say which procedure you're using. If JMP I have no clue.

The approach is similar as the Axis controls the scaling of charts. If using the Gcontour procedure specify log axis in AXIS statements then associate the Haxis and Vaxis with the appropriate Axis statement.

Axis1 logbase=10;

then in Gcontour plot statement

Haxis=axis1

Vaxis=axis1

with minimal specifications.

If in Sgraphics then options yaxisopts=(logopts=(base=10)) and similar for X

Each approach has different options for tick marks displayed and intervals

Sorry. Yes I'm using JMP10 making a contour plot like the one below
