我阅读了以前的解决方案,但无法使其中任何一个工作。我想为每个子图都有一个全球图例。 此副区的斧目的是通过预定义的函数“get_plot”产生了一个预定义的类 “The_predefined_plotting_class”大致是这样的:具有不同内容的子图的全球图例
该函数返回斧头对象和每斧对象具有多个从原始“数据文件”的多列中“绘制”/绘图。
在我在这个网站上找到的解决方案之一,我读,我可以用:
,使全球的传奇。不幸的是,我不知道如何追加单个的ax对象(或其中的数据)来处理这个工作。 每个地块包含一些相同的列名称和一些不同。如果一个条目/名称存在于许多子图中,则只应打印一次。

,我真的很抱歉,我不得不使用图片,但无论我做了webside没有让我后我的代码即使是在预览窗口中显示正确(屏幕截图来自此窗口)
EDIT2
如果我不喜欢这样写道:
lines=[]
labels=[]
for idata, datafile in enumerate(datafiles):
MYData = The_predefined_plotting_class.from_file(datafile)
axis[idata] = The_predefined_plotting_class.get_plot(*kwargs)
h, l = axis[idata].get_legend_handles_labels()
lines.append(h)
labels.append(l)
LINES=[]
LABELS=[]
for i in range(0, nrows):
LINES+=lines[i]
LABELS+=labels[i]
plt.legend(LINES, LABELS, loc="upper left", bbox_to_anchor=[0, 1],ncol=3, shadow=True, title="Legend", fancybox=True)
plt.show()
然后,它会显示所有数据。某些数据具有相同的行和标签处理程序。如果在这两个列表中,我现在留下的问题是遍历两个列表并删除一个条目元组(LINES [j]; LABELS [j])=(LINES [i]; LABELS [i])存在两次(并且只有这样)。优选的第一项:
EDIT3
labels =[]
lines = []
h=["Cat","Mouse","Dog","Cat","Cat","Kangaroo","Dog"]
l=["black","white","brown","white","black","yellow","brown"]
for handle, label in zip(h, l):
if label not in labels :
lines.append(handle)
labels.append(label)
print "The disired Output is :"
print '["Cat","Mouse","Dog","Cat","Kangaroo"]'
print '["black","white","brown","white","yellow"]'
print "currently you get:"
print lines
print labels

我添加了一个 “最低” 工作的例子应该包含发生在我的真实数据所有可能的情况。
lines=[]
labels=[]
legend_properties = {'weight':'bold','size':10}
# Example data

这是部分形成在产生实际的地块有问题的脚本。 “列”只包含要绘制的实际数据的名称。
# add plots
ic = 0
for col in columns:
if col == "envelope":
ax.plot(self.data.index, self.data.envelope,
linewidth=LINEWIDTH_envelope, c=last_color, label="")
elif col == "Exp":
ax.plot(self.data.index, self.data.Exp, c=first_color, linestyle="",
label="Exp", marker="o", markersize=MARKERSIZE)
else:
color = used_colors[ic % len(used_colors)]
if fill and "BG" in self.data.columns:
ax.fill_between(self.data.index, self.data.BG,
self.data[col], label=col, alpha=ALPHA,
color=color)
else:
ax.plot(self.data.index, self.data[col], linewidth=LINEWIDTH,
c=color, label=col)
ic += 1

我想基于这样的想法我这里介绍找到一个解决办法:
不幸的是什么工作了包含字符串为不起作用两个列表看起来好像是艺术家。
import matplotlib.pyplot as plt
import numpy as np
LI=[]

b = np.cos(2 * np.pi * x2)
c = np.cos(5 * np.pi * x1) * np.exp(-x1)
c2 = np.cos(5 * np.pi * x1**2) * np.exp(-x1)
d = np.cos(2 * np.pi * x2)
d2 = np.cos(2 * np.pi * x2-1)
e = x1*5
e2 = -x1*5
f = np.exp(x1)-e
f2 = (np.exp(x1)-e)/2

axis[0].plot(x1, e, 'k--', label='Label1',color="green")

axis[2].plot(x2, d2, 'D', label='Label2',color="green")
axis[3].plot(x1, f, 'H', label='Label1',color="green")
axis[3].plot(x1, f2, 'D', label='Label2',color="green")
for i in range(nrows):
print i
h, l = axis[i].get_legend_handles_labels()
for hl in zip(h,l):
if hl not in LI:
LI.append(hl)
lines.append(LI[-1][0])
labels.append(LI[-1][1])
print LI
# only 3 Legend entrys Label1 , Label2 and Label3 are visible .. Differences in cloors and markers are ignored
plt.legend(handles=lines, labels=labels,bbox_to_anchor=(0., nrows+.02, 1., .102), loc=3,ncol=3, prop=legend_properties,mode="expand", borderaxespad=0.,frameon=False,framealpha=0.0)
plt.show()
我认为问题是,只对内存ADRESS字符串中
if hl not in LI:
不是“H”的实际内容进行比较?基于ImportanceOfBeingErnest的解释

这里我的真实数据反映更好,因为我有两个matplotlib.collections.PolyCollection)和matplotlib.lines.Line2D这些对象需要进行比较。
在问题解决方案中没有链接这个工作了吗?我建议一个简单的'ax.legend(bbox_to_anchor =(1.05,0),loc ='lower center',borderaxespad = 0。)' –
你需要手动输入代码,不知何故,你粘贴的截图代码。 – ngoldbaum
如果我按照你的建议得到:AttributeError:'numpy.ndarray'对象没有属性'legend'!我在上面添加了一个问题。 – NorrinRadd
