Kader,
What versions of Python/Matplotlib are you running? This example works as
expected:
fig = plt.figure(figsize=(9, 9))
skew = SkewT(fig, rotation=45)
skew.plot([1000, 100], [25, -125], color='tab:red')
skew.plot_dry_adiabats()
skew.plot_moist_adiabats()
skew.plot_mixing_lines()
plt.twinx()
What are you wanting to use the secondary y-axis for? Knowing what the end
goal is may lead us to a better path to get there.
Thank you,

John,
I thank you for your advices and the informations.
I tried but It's not work.
frame1 = plt.gca()
frame1.axes.get_xaxis().set_ticks([])
frame1.axes.get_yaxis().set_ticks([])
But:
frame1.axes.get_xaxis().set_ticklabels([])
frame1.axes.get_yaxis().set_ticklabels([])
remove the old labels(Temperature) from xaxis.
Best Regards.

Kader,
When you call twinx, a second set of x and y labels are created. You can
turn the labels off if you’d like
frame1.axes.get_xaxis().set_ticks([])
frame1.axes.get_yaxis().set_ticks([])
I’d also recommend not importing metpy.calc.thermo. When you import
metpy.calc all of those functions are included. See this tutorial:
https://unidata.github.io/MetPy/latest/tutorials/upperair_soundings.html#sphx-glr-tutorials-upperair-soundings-py

Thank you John,
I send you as an attachment the code. Other calculations are included that
are not part of the plot.

Kader,
Would you mind sharing the code you are using to create this plot? Without
seeing it, I’m unable to tell what is causing the labels to be doubled.
Thank you,

HI John,
Thank you for your help, I have another question regarding the plot.
By making this graph, I have the y-axis indices that are duplicated and
superimposed with those of the x-axis
I send you an example in attachment.
Best Regards.

Hello Kader,
Are you running the current master branch from GitHub? The CAPE/CIN
calculation was just added and is not in an official release of MetPy yet.
The calling syntax would look something like:
import metpy.calc as mpcalc
cape, cin = mpcalc.cape_cin(…….)
As you’ve probably noticed, this is a recent addition (as of this week) to
MetPy. We’re working on some convenience functions to help with surface
based, mixed layer, and most unstable CAPE, as well as doing the virtual
temperature correction for you. This base function assumes nothing, so
don’t forget to apply the relevant corrections to your data.
As far as SRH, there is a PR for it that will hopefully be merged soon (
https://github.com/Unidata/MetPy/pull/462). The team will be at the SciPy
conference in a few weeks hosting a sprint in which we hope to work towards
getting these additional calculations in master.

Hello,
I'm trying to calculate cape, cin values with cape_cin function which can
be found in MetPy thermo module,
but I encounter the error: *AttributeError: 'module' object has no
attribute 'cape_cin'*
Also I wanrt to calculate the SRH "Storm Relative Helicity", is there a
formula in MetPy to do that?
Kind Regards
