Re: [Pgfplots-features] Smith chart coordinate systems

[Christian F. <cfe...@go...>]

Hi Chris,

thanks for the detailed bug report.

This is a side-effect of a feature activated by 'compat=1.11': it 
switches the default coordinate system to "axis cs". Unfortunately, the 
regression regarding smith charts was not detected earlier.

A workaround is to use 'compat=1.10' in the preamble.

I will take care of the issue.

Kind regards

Christian
