           Summary: Transforming log-scaled axes is not intuitive
           Product: kst
           Version: 1.8.0
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst at kde.org
        ReportedBy: bug.zilla.vynce at neverbox.com

Version:           1.8.0 (using 3.5.10-3.fc10 Fedora, Fedora release 10
Compiler:          Target: i386-redhat-linux
OS:                Linux (i686) release

1. Setup a plot. The vectors should have values in the 1000's.
2. Set the y axis to log scale.
3. Enable the right-axis transform and set the expression to y/1000.
4. The transform expression is applied to exponent of the left axis instead of
the actual value.

For example:
I have a label on the left axis that says 10^5. If I set the transform
expression to y/1000, I expect the corresponding label on the right axis to be
100. Instead it is 0.005. If I change the transform expression to 10^(y-3), it
works correctly. The problem is that if you then disable log scaling, the
transformation is wrong again and needs to be set back to y/1000. I don't think
that toggling log scaling on and off should affect the transformed axis.
