2.1 使用 (on, off) 序列 最简单的自定义线型方法是使用 (on, off) 序列。这个序列定义了线段的长度和间隔的长度,单位是点(points)。例如: importmatplotlib.pyplotaspltimportnumpyasnp x=np.linspace(0,10,100)y=np.sin(x)plt.figure(figsize=(10,6))plt.plot(x,y,linestyle=(0,(5,5)),label='...

To make a legend for lines which already exist on the axes (via plot for instance), simply call this function with an iterable of strings, one for each legend item. For example:: ax.plot([1, 2, 3]) ax.legend(['A simple line'])Note:This way of using is discouraged, because the...
