python检查数字是2d还是3d [英] python check if figure is 2d or 3d

问题描述

在带有图形的matlab中，要检查它是3D图形还是2D图形，我使用:

In matlab with a figure, to check if it is 3D figure or 2D figure I use:

V=axis;

，然后检查V的分量数(2d图形为4，3d图形为6). 我该如何使用python和matplotlib来实现这一点?

and check the number of components of V (4 for 2d figure, 6 for 3d figure). How can i implement this with python and matplotlib?

推荐答案

您可以使用轴的name.

plt.gca().name   or   ax.name

如果ax是轴.

3D轴的名称为"3d". 2D轴的名称将为"rectilinear"，"polar"或其他名称，具体取决于绘图的类型.

A 3D axes' name will be "3d". A 2D axes' name will be "rectilinear", "polar" or some other name depending on the type of plot.

因此您可以检查

if  ax.name == "3d":
    # axes is 3D, do something
else:
    # axes is not 3D, do something else

您还可以根据对

You can also check for the limits, as proposed in an answer to the question this is a duplicate of. In this way you would get the limits

def get_limits(ax):
    xlim = ax.get_xlim()
    ylim = ax.get_ylim()
    if hasattr(ax, 'get_zlim'): 
        zlim = ax.get_zlim()
        return xlim, ylim, zlim
    else:
        return xlim, ylim
