使用seaborn和大 pandas 密谋防止重叠的酒吧 [英] prevent overlapping bars using seaborn with pandas plotting

问题描述

我正在尝试使用pandas plotting创建一个带有seaborn导入的堆叠水平条形图。我想删除栏之间的空格，但也没有栏重叠。这就是我尝试过的：

I am trying to use pandas plotting to create a stacked horizontal barplot with a seaborn import. I would like to remove space between the bars, but also not have the bars overlap. This is what I've tried:

import pandas as pd
import numpy as pd
import seaborn as sns

df = pd.DataFrame(np.random.rand(15, 3))
df.plot.barh(stacked=True, width=1)

这似乎没有导入seaborn，虽然我喜欢seaborn风格，它通常是我工作的ipython笔记本中的导入这可能吗？

This seems to work without importing seaborn, though I like the seaborn style and it is usually an import in the ipython notebook I am working in is this possible?

推荐答案

如果将条形线宽设置为seaborn样式，则使用matplotlib默认值也可以看到此工件：

This artifact is also visible with matplotlib defaults if you set the bar linewidth to what seaborn style has:

import pandas as pd
import numpy as np

df = pd.DataFrame(np.random.rand(15, 3))
df.plot(stacked=True, width=1, kind="barh", lw=.5)

一个解决方案是将条线增加到matplotlib默认值的大致位置：

A solution would be to increase the bar lines back to roughly where the matplotlib defaults are:

import pandas as pd
import numpy as np
import seaborn as sns

df = pd.DataFrame(np.random.rand(15, 3))
df.plot(stacked=True, width=1, kind="barh", lw=1)
