Error when using plot_parameter_stability

[AinhoaOleaga]

Hello,

When I try to use the function plot_parameter_stability on a pandas.core.series.Series I have a shape problem :
-- "x and y must have same first dimension, but have shapes (100,) and (1,)".
I do not understand why I have this problem as the line of code that I used is :
-- "pyextremes.plot_parameter_stability(ts = data)"
nothing more nothing less.
The data is of shape (50241,) but it shouldn't be a problem.
After the error I have the basis of the plots for shape and modified scale but no plot inside.

Thank you in advance for your help.

Regards

Please provide exact code and data you used, I cannot say anything until I reproduce your error. And tell me which version of pyextremes you are using.

Hello,

I use the version 2.0.0.
Unfortunately I cannot provide you with the dataset but the error log looks as follows :

The code was :
pye.plot_parameter_stability(ts = dataset)

It's OK if you cannot provide original dataset. Perhaps you could create some dummy data which you can share with me to reproduce the error - it can be randomly generated as long as we use the same thing. Your error log doesn't help because this function works fine on my end for my test data: https://github.com/georgebv/pyextremes-notebooks/tree/master/data

I also advise using latest version - 2.2.4. Several important fixes were made since 2.0.0.

After downloading your repo to use the latest version everything is solved ! Thank you for your help :)
