E.g. pandas.DataFrame.plot, title : string. Now that there are a varying number of plots this isn't as simple since I cannot find a nice formula for determining how much to shrink the plot and how far down to put the legend so it is not being cut off or overlapping the axis. Legend location¶. Functions in the Matplotlib-C++ library are designed to work with a generic vector type where possible. In this tutorial, we're going to cover legends, titles, and labels within Matplotlib. Now that there are a varying number of plots this isn't as simple since I cannot find a nice formula for determining how much to shrink the plot and how far down to put the legend so it is not being cut off or overlapping the axis. The main issue with legends is typically that the legend gets in the way of data. The following code shows how to do it. The following code shows how to do it. Matplotlib legend outside. How to put the legend out of the plot. loc="upper right" places the legend in the upper right corner of the bounding box, which by default extents from (0,0) to (1,1) in axes coordinates (or in bounding box notation (x0,y0, width, height)=(0,0,1,1)). 0.0 is at the base the legend text, and 1.0 is at the top.

A lot of times, graphs can be self-explanatory, but having a title to the graph, labels on the axis, and a legend that explains what each line is can be necessary. I would like to have legend located outside of the of the graph at the bottom. fancybox=True and set_alpha(0.5) made the legend slightly transparent so these points could be viewed. To create a scatter plot with a legend one may use a loop and create one scatter plot per item to appear in the legend and set the label accordingly. This can be useful if e.g. bbox_to_anchor kwarg sets legend to be centered on X axis and below that axis. When using matplotlib in a Jupyter Notebook with the magic %matplotlib notebook, legends placed outside of the axis are cut off. loc="upper right" places the legend in the upper right corner of the bounding box, which by default extents from (0,0) to (1,1) in axes coordinates (or in bounding box notation (x0,y0, width, height)=(0,0,1,1)).
