It's a simple thing but I've searched for quite a while without success: I want to customise a figure legend by reversing the horizontal order of the symbols and labels.
In Gnuplot, this is simply achieved by set key reverse. Example: change x data1
to data1 x
. In matplotlib, there seems to be no user-friendly solution. Thus, I thought about changing a kind of handle anchor or just shifting the handle's position, but couldn't find any point to start with.
To change the position of a legend in Matplotlib, you can use the plt. legend() function. The default location is “best” – which is where Matplotlib automatically finds a location for the legend based on where it avoids covering any data points.
In Matplotlib, to set a legend outside of a plot you have to use the legend() method and pass the bbox_to_anchor attribute to it. We use the bbox_to_anchor=(x,y) attribute. Here x and y specify the coordinates of the legend.
Change order of items in the legend The above order of elements in the legend region can be changed by the gca method that uses another sub-method called get_legend_handles_labels method. These handles and labels lists are passed as parameters to legend method with order of indexes.
The requested feature is already there, as the keyword markerfirst
of the legend
command.
plt.plot([1,2],[3,4], label='labeltext')
plt.legend(markerfirst=False)
plt.show()
If you want to make it your default behaviour, you can change the value of legend.markerfirst
in rcParams
, see customizing matplotlib.
