Hi Fred,
your data contain the value x=0. Thus, plot.setLimitsToFit forces the
plot to include the value x=0, which forces the x axis to be linear, not
logarithmic.
If you have only positive data, or if you don't call setLimitsToFit,
useTemplate with Plot.COPY_AXIS_STYLE keeps the axis logarithmic.

Greeting,
I am trying to maintain the logarithmic axis through successive plots, see
below. To reproduce, you...
Run the below plugin.
Click "Press me"
Choose More>> Set Range...
Set X From to 0.1
Set Log X Axis
Click OK
Click "Press me"
The X axis is no longer logarithmic.
Choosing More>> Set Range...
reveals that X From is now "0" again, albeit Log X Axis is still set...
Q: Is just X_RANGE required for my requirement, or is COPY_AXIS_STYLE also
required?
