matplotlib取消轴对象上的图例

Question

I am using an external module which automatically adds a legend to the plot. I would like to know if there is a way of turning off the legend, something like ax.set_legend(False).

I could fix it by hacking the module but I would rather not do that.

example:

 f = plt.figure()
 ax = f.add_subplot(111)

 externalfunction(ax)

 # in the function ax.legend() has been called
 # would like to turn off the legend here

 plt.show()

Update:

I have raised a github issue for this https://github.com/matplotlib/matplotlib/issues/2792

Answer 1

你需要改变你的传奇的可见性，试试这个： ax.legend().set_visible(False)

Answer 2

This can also be accomplished by setting the legend_ attribute of the axis to None . Note the trailing underscore. Eg

x, y = np.random.randn(2, 30)
ax = plt.gca()
ax.plot(x, y, label="data")
ax.legend()
ax.legend_ = None

It sounds like future matplotlib versions will have a more officially-sanctioned method for removing the axis, but this should work in the meantime/if stuck on an older version.
