Hi Malgorzata,

I’m not able to reproduce your plot because the snippet of code you pasted there does not appear to be complete (many of the variables are not defined). Would it be possible to directly attach your script/Jupyter notebook? That would allow us to try it out to see what’s happening.

Thanks,  
Paul
