拥有一个独立的示例(可能包含虚构数据)将有所帮助,以便人们可以立即运行它。这是一个根据您发布的内容修改的独立示例,对我来说效果很好ipython -pylab
,最近有 Matplotlib 的 svn 修订版;我认为一些与图例相关的错误最近已得到修复。
colors = (i + j for j in 'o<.' for i in 'bgrcmyk')
labels = 'one two three four five six seven eight nine ten'.split()
x = linspace(0, 2*pi, 3000)
d = (2+random((2,3000))) * c_[sin(x), cos(x)].T
for i, l, c in zip(range(10), labels, colors):
start, stop = i * 300, (i + 1) * 300
plot(d[0, start:stop], d[1, start:stop], c, label=l)
legend(loc='lower left')
show()
这就是我得到的:

假设该错误与自动图例功能相关,您可以通过明确说明您想要在图例中显示的内容来解决该问题:
colors = (i + j for j in 'o<.' for i in 'bgrcmyk')
labels = 'one two three four five six seven eight nine ten'.split()
x = linspace(0, 2*pi, 3000)
d = (2+random((2,3000))) * c_[sin(x), cos(x)].T
lg = []
for i, l, c in zip(range(10), labels, colors):
start, stop = i * 300, (i + 1) * 300
handle = plot(d[0, start:stop], d[1, start:stop], c, label=l)
lg.append(handle)
legend(lg, labels, loc='lower left')
show()
