当图相对于图的边缘运行时增加边距 [英] Add margin when plots run against the edge of the graph

问题描述

通常当我在matplotlib中进行绘图时，会得到如下图:

Often when I plot in matplotlib, I get graphs like this:

您看不到该函数，因为它在图的边缘运行.

You can't see the function because it runs against the edge of the plot.

在这些情况下，是否有任何方法可以自动添加一些余量，使它们看起来像这样:

Is there any way to automatically add some margin in these cases, so that they look like this:

推荐答案

您可以使用ax.margins()设置

You can use ax.margins() to set the margins. Example:

In [1]: fig, ax = plt.subplots()

In [2]: ax.plot(np.arange(10), '-o')
Out[2]: [<matplotlib.lines.Line2D at 0x302fb50>]

In [1]: fig, ax = plt.subplots()

In [2]: ax.margins(0.05)

In [3]: ax.plot(np.arange(10), '-o')
Out[3]: [<matplotlib.lines.Line2D at 0x302fb50>]

您还可以仅设置x或y边距.但是，它似乎不是matplotlibrc选项，因此您可以简单地将其设置为默认行为(因此它不是完全自动的).我打开了 github问题以请求此操作.

You can also set only the x- or the y-margin. However it doesn't seem to be a matplotlibrc option so that you can simply make this the default behaviour (so it isn't fully automatically). I opened a github issue to request this.
