In the plot, the blue fill should be between the red and green line. Matplotlib: beautiful plots with style Example charts using the Matplotlib BMH style Matplotlib is both powerful and complex: being able to adjust every aspect of a plot is powerful, but it's often time-consuming and complex to create a beautiful plot. It has both an easy-to-use programming interface, and a rich graphical user interface for manipulating the plot after it has been drawn. For a more advanced drawing library for PIL, see the aggdraw module. One would therefore need to interpolate them such that the fill_betweenx can use the same y values for the fill between the two curves that initially have different y values for different x values. ax : a matplotlib Axes instance The axes to plot on. Here we'll perform a simple Gaussian process regression , using the Scikit-Learn API (see Introducing Scikit-Learn for details). Lines 117-121 compile our TraffigSignNet model with the Adam optimizer and learning rate decay. markerfacecolor or mfc Controls marker fill color Any valid matplotlib color label A label used to identify the line.
