matplotlib.lines.Line2D类是matplotlib中的曲线类(基类是matplotlib.artist.Artist),它可以有各种各样的颜色、类型、以及标注等等。它的构造函数为: Line2D(xdata, ydata, linewidth=None, linestyle=None, color=None, marker=None, markersize=None, markeredgewidth =None, markeredgecolor=None, markerfacecolor =...
It's a shortcut string notation described in the *Notes* section below. >>> plot(x, y) # plot x and y using default line style and color >>> plot(x, y, 'bo') # plot x and y using blue circle markers >>> plot(y) # plot y using x as index array 0..N-1 >>> plot(...

在这个例子中,ax是上面的fig.add_subplot调用创建的Axes实例(记住Subplot只是Axes的一个子类),当你调用ax.plot时,它创建一个Line2D实例并将其添加到Axes.lines列表中。 在下面的 ipython 交互式会话中,你可以看到Axes.lines列表的长度为 1,并且包含由line, = ax.plot...调用返回的相同线条: 代码语言:javascript...
