Setting the Y axis calibration to be logrithmic gives
vastly incorrect results.

I set the axis to vary from 1e-3 to 1 (the limits of
the axis) and got results of ~1e-5 and ~1e-7 for the
same point. The differing values came after
recalibrating the Y axis.

This problem existed with 2.2.1 (although I didn't
realize it) and currently with 2.3.0.

    I have found the bug and will try and get it fixed as soon
    as possible.

    In the case of the Y axis, I accidentally used Math.log()
    (natural log) rather than MathTools.log10() (base 10 log).
    Big difference. I managed to get the X-axis right.

    Thanks for catching this!

    This has been fixed in the 2.3.1 release.
