This obtains the output you show in the image.

fig, ax = plt.subplots()

ax.plot(np.arange(0.0,12.0,2.0), 'r-')
ax.plot(np.arange(10.0,0.5,-1.8), 'g-')

handles, labels = ax.get_legend_handles_labels()
labels = ['P = increasing', ' = decreasing']

ax.legend(handles, labels, loc = 'center right', markerfirst = False)
plt.show()

enter image description here

You can try:

plt.legend(markerfirst = False)

From documentation:

markerfirst : bool

If True, legend marker is placed to the left of the legend label. If False, legend marker is placed to the right of the legend label. Default is True.
