To learn more, see our tips on writing great answers. of view of the colors used by default. Let's change up the linear_sequence a bit to make it observable once we plot both: This time around, we'll have to use the OOP interface, since we're creating a new Axes instance. Matplotlib converts "CN" colors to RGBA when drawing Artists. To solve I can use a combination of linestyles and markers when I have more than say 4-5 lines with same color. How do I change the size of figures drawn with Matplotlib? or change altogether the default editing your .matplotlibrc file. It may help someone. And the second way is when we want to add different titles to each plot or subplot, then we use the title() function of pyplot module. In Matplotlib, we can draw multiple graphs in a single plot in two ways. We can plot them both linearly, simply by plotting them on different Axes objects, in the same position, each of which set the Y-axis ticks automatically to accommodate for the data we're feeding in: We've again created another Axes in the same position as the first one, so we can plot on the same place in the Figure but different Axes objects, which allows us to set values for each Y-axis individually.
