Python 改进子批次中饼图的标记
我正在绘制一个包含三个子图的图形:Python 改进子批次中饼图的标记,python,matplotlib,plot,charts,pie-chart,Python,Matplotlib,Plot,Charts,Pie Chart,我正在绘制一个包含三个子图的图形: fig = plt.figure(fignum) ax11 = plt.subplot2grid((2,2), (0,0)) ax12 = plt.subplot2grid((2,2), (0,1)) ax13 = plt.subplot2grid((2,2), (1,0), colspan=2) ax13.axis('off') 我使用熊猫作为我的数据,我想绘制一个条形图、一个饼图和一个表格。我正在这样做: d = pd.Series(data,index
fig = plt.figure(fignum)
ax11 = plt.subplot2grid((2,2), (0,0))
ax12 = plt.subplot2grid((2,2), (0,1))
ax13 = plt.subplot2grid((2,2), (1,0), colspan=2)
ax13.axis('off')
我使用熊猫作为我的数据,我想绘制一个条形图、一个饼图和一个表格。我正在这样做:
d = pd.Series(data,index)
#plotting the first subplot
d.plot(kind='bar',ax=ax11)
#plotting the second one and adjusting size of labels and percentages
(wedges, texts, autotexts) = ax12.pie(d,labels=d.index,autopct='%1.1f%%')
ax12.axis('equal')
for t in texts:
t.set_size(7)
for t in autotexts:
t.set_size(7)
#plotting the third axes, the table
ax13.table(cellText=table,colLabels=columns,loc='bottom')
结果是这样的:
如何使饼图看起来更好,不让标签重叠?我尝试添加图例,但它掩盖了图表,我甚至不知道它是否在我指定的位置结束:
ax12.legend(index,loc='lower right',fontsize=7)
有没有办法将图例向下移动到饼图下的空白处?一旦图例看起来不错,我将从饼图本身删除标签。
bbox\u to\u anchor
用于将图例放置在图形画布上
见:
尽管您可以跳过图例并通过调整它来提高饼图的可读性。我可以想出三种方法,但这并不是一个详尽的清单:
pandas
中可能有一种方法可以实现这一点labeldistance
用于控制标签到图表的距离explode
参数传递,可以偏移每个切片的位置ax12 = plt.subplot2grid((2,2), (0,1))
labels = ["bewarfefvl","easdfgvagfvd","asasdfve.sd",
"rgdegaf","adfewga","qargw","qaerghrttw","errrrd","ejjjjd"]
ax12.pie( [10,20,30,5,5,6,4,10,10], [0,0,0.0,0.1,0.3,.5,0,0,0],
labels = labels, labeldistance=1.2)
ax12 = plt.subplot2grid((2,2), (0,1))
labels = ["bewarfefvl","easdfgvagfvd","asasdfve.sd",
"rgdegaf","adfewga","qargw","qaerghrttw","errrrd","ejjjjd"]
ax12.pie( [10,20,30,5,5,6,4,10,10], [0,0,0.0,0.1,0.3,.5,0,0,0],
labels = labels, labeldistance=1.2)
