当我为3d图形设置相等的长宽比时,z轴不会更改为“相等”。所以这: fig = pylab.figure() mesFig = fig.gca(projection='3d', adjustable='box') mesFig.axis('equal') mesFig.plot(xC, yC, zC, 'r.') mesFig.plot(xO, yO, zO, 'b.') pyplot.show() 给我以下内容: 在此处输入图片说明 显然...
aspect : {'equal', 'auto'} or float, optional Controls the aspect ratio of the axes. The aspect is of particular relevance for images since it may distort the image, i.e. pixel will not be square. This parameter is a shortcut for explicitly calling `.Axes.set_aspect`. See there for...
plt.title("Simple Plot") plt.legend() 2、matplotlib中的概念 下面这张图是官网的一张图,指明了很多概念,基本上常用的我们都能看到,看起来大部分也都能理解 Figure(容器) 整个图像称为Figure, Figure用于保存返回的Axes(坐标域), 一个Figure可以包含任意数量的Axes,可以理解为一个容器。
