plot(x, np.sin(x), '-') plt.plot(x, np.cos(x), '--'); Figure 4-1. Basic plotting example Saving Figures to File One nice feature of Matplotlib is the ability to save figures in a wide variety of formats. You can save a figure using the savefig() command. For example, to ...
fontweight ='bold',size=14) To increase the size of the figure, we use the figure() method and pass figsize parameter to it with the width and height of the plot. To plot a graph, we use the scatter() function. To set labels at axes, we use xlabel() and ylabel() functions. ...
