[matplotlib-devel] matplot.axis() range question

[Stefan K. <pon...@ya...>]

When I run the script below, the range tuple is 

[0.0, 1.0, 0.0, 1.0]
 
but the data has an actual range more like [ 0, 6.8, 0, 1], the plot
looks correct, which is good, but the range tuple is wrong.  It seems
to work fine with simple data examples but breaks with this data..

This is with Matplotlib v0.54.2

thanks,
S
