How to set log scale as default in CurveWidget (ie not changing to it interactively)

[yann lecoq]

Hello and thanks for this great piece of software.

I'm trying to make a plot from a Python program that immediately appears in
log scale with guiqwt.plot.CurveWidget (ie without having to interactively
change the axis setups). I use python 2.7 with QT designer4.

I am probably missing something obvious, but I couldn't find functions in
this class that looks like they can setup properties of the plot from the
source code (ie similar to set_axis_scale() in BasePlot for exemple). Is
there any way to do so ?

Thanks for your help, and sorry if that was obvious.

How are you trying to call set_axis_scale()?
If your CurveWidget is called curvewidget lets say, you should only need to call:

curvewidget.plot.set_axis_scale(axis_id, scale) where axis_id is one of:
‘top’,’bottom’,’left’,’right’
And scale is either:
‘lin’ or ‘log’

Thank you very much Russ for your help. This did what was intended.
Retrospectively I see that I was indeed missing something quite simple...

Thanks again
