[Matplotlib-users] Connect plot in Contourf when there are missing values(nan)

I am plotting x, y, z values using contourf plots. However I have some
missing z values (nan). All these regions are shown as blanks and the graph
looks diconnected.

Is there a way for the plot to have connected gaps? Plotly has an option to
connect gaps with smooth transitions?

Do we have an equivalent of this in matlotlib contourf plots?

I just found this unread in my email stack--did anyone reply to you already? If not, the answer to your question is no, matplotlib declines to fill bad value gaps via interpolation. We believe that as a plotting library, we should generally plot the data as provided, leaving it to the user to interpolate over gaps, if that is desired.
