API Changes in 2.1.2#
Figure.legend
no longer checks for repeated lines to ignore#
matplotlib.figure.Figure.legend
used to check if a line had the
same label as an existing legend entry. If it also had the same line color
or marker color legend didn't add a new entry for that line. However, the
list of conditions was incomplete, didn't handle RGB tuples,
didn't handle linewidths or linestyles etc.
This logic did not exist in axes.Axes.legend
. It was included (erroneously)
in Matplotlib 2.1.1 when the legend argument parsing was unified PR #9324.
This change removes that check in axes.Axes.legend
again to restore the old
behavior.
This logic has also been dropped from Figure.legend
, where it
was previously undocumented. Repeated
lines with the same label will now each have an entry in the legend. If
you do not want the duplicate entries, don't add a label to the line, or
prepend the label with an underscore.
