This may be useful if you have many plots and want to be able to easily scan the code but not display the names in the plots. If you input loc=(2, 2) you get a very stange looking graph because matplotlib places the legend at double the length and double the height of the axes. So setting loc=(0.5, 0.5) will place the bottom left corner half way along the x-axis and half way along the y-axis. This is default for all artists, so calling Axes.legend without Write a Python program to plot two or more lines with legends, different widths and colors.
