Matplotlib:无法同时关闭轴和设置面色吗? [英] Matplotlib: Turning axes off and setting facecolor at the same time not possible?

问题描述

有人可以解释为什么在关闭轴的情况下，这个简单的代码不会执行facecolor命令吗?

can someone explain why this simple code wont execute the facecolor command while setting the axis off?

fig = plt.figure(1)
ax = fig.add_subplot(211, facecolor=(0,0,0), aspect='equal')
ax.scatter(np.random.random(10000), np.random.random(10000), c="gray", s=0.25)
ax.axes.set_axis_off()

提前致谢！

推荐答案

背景补丁是轴的一部分.因此，如果轴已关闭，则背景色块也将关闭.

The background patch is part of the axes. So if the axes is turned off, so will the background patch.

一些选项:

ax = fig.add_subplot(211, facecolor=(0,0,0), aspect='equal')
ax.set_axis_off()
ax.add_artist(ax.patch)
ax.patch.set_zorder(-1)

创建新补丁

ax = fig.add_subplot(211, facecolor=(0,0,0), aspect='equal')
ax.set_axis_off()
ax.add_patch(plt.Rectangle((0,0), 1, 1, facecolor=(0,0,0),
                           transform=ax.transAxes, zorder=-1))

使轴脊和刻度不可见

...但保持轴打开.

Turn axis spines and ticks invisible

...but keep the axis on.

ax = fig.add_subplot(211, facecolor=(0,0,0), aspect='equal')
for spine in ax.spines.values():
    spine.set_visible(False)
ax.tick_params(bottom=False, labelbottom=False,
               left=False, labelleft=False)
