I create legend in my chart this way:
legend_handles.append(matplotlib.patches.Patch(color=color1, label='group1'))
legend_handles.append(matplotlib.patches.Patch(color=color2, label='group2'))
ax.legend(loc='upper center', handles=legend_handles, fontsize='small')
This results in the legend items stacked vertically (top-bottom), while I would like to put them horizontally left to right.
How can I do that?

How to show legend elements horizontally in Matplotlib? Set the figure size and adjust the padding between and around the subplots. Using plot () method, plot lines with the labels line1, line2 and line3. Place a legend on the figure using legend () method, with number of labels for ncol value in the argument.

class matplotlib.patches.Patch(edgecolor=None, facecolor=None, color=None, linewidth=None, linestyle=None, antialiased=None, hatch=None, fill=True, capstyle=None, joinstyle=None, **kwargs) [source] # A patch is a 2D artist with a face color and an edge color.
The easiest way offered by matplotlib in my opinion is to define the properties of the legend using prop size to increase/decrease the legend size. You just need to do the following where you can choose the 'size' as preferred. plt.legend (handles= [patch_1, patch_2], loc='best', prop= {'size': 24})
There is an argument determining the number of columns ncol=.
ax.legend(loc='upper center', handles=legend_handles, fontsize='small', ncol=2)
This should do the trick. Got it from this thread.
