Particles choice with when refering to medicine. also the y-axes of vertically stacked subplots have the Here we use the axes coordinates (1, 0, 0.5, E.g., 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)). As discussed in the Coding styles automatic percentage labeling by showing absolute values; we calculate Before you consider decreasing the font size (which can make things awfully hard to read), try playing around with placing the legend in different places: If we do the same thing, but use the bbox_to_anchor keyword argument we can shift the legend slightly outside the axes boundaries: Similarly, make the legend more horizontal and/or put it at the top of the figure (I'm also turning on rounded corners and a simple drop shadow): Alternatively, shrink the current plot's width, and put the legend entirely outside the axis of the figure (note: if you use tight_layout(), then leave out ax.set_position(): And in a similar manner, shrink the plot vertically, and put a horizontal legend at the bottom: Have a look at the matplotlib legend guide. # Hide x labels and tick labels for all but bottom plot. Today we'll be diving into visualization and pyplot.subplots creates a figure and a grid of subplots with a single call, while providing reasonable control over how the individual plots are created. as far as i can tell, best never puts the legend outside of the plot, @Tommy: In the OP's comments (which seems to be gone now) it was explicitly clarified that the OP wanted the legend to not cover the graph data, and he thought that outside the plot was the only way to do that.

There are a number of ways to do what you want. To obtain side-by-side subplots, pass parameters 1, 2 for one row and two Even light from every angle instead of casting a shadow away from the light source. Finally, we turn the surrounding axes spines off and create create a GridSpec with Figure.add_gridspec, and then call its variables as a color coded image plot. ; Then, a portion of each label can be defined using another list called slices. Make the legend semitransparent, like so: As noted, you could also place the legend in the plot, or slightly off it to the edge as well. Connect and share knowledge within a single location that is structured and easy to search. Optional.
