To add legends in a subplot, we can take the following Steps −Using numpy, create points for x, y1, y2 and y3.Create a figure and a set of subplots, using the subplots() method, considering 3 subplots.Plot the curve on all the subplots(3), with different labels, colors. To place the legend ... Read More

We can change the color of the axis, ticks and labels, using ax.spines['left'].set_color('red') and ax.spines['top'].set_color('red') statements. To change the color of the axis, ticks, and labels for a plot in matplotlib, we can take the following steps −Create a new figure, or activate an existing figure, using plt.figure().Add an axis ...
