问题描述
假设我的DataFrame的列为['X_Axis','col_2','col_3',...,'col_n',]
suppose I have DataFrame with columns ['X_Axis','col_2','col_3',...,'col_n',]
我需要在X轴上绘制第一列,并在Y轴上绘制.仅供参考:所有值均已根据X轴分组,X轴值的范围为0-25
,所有其他列值均已归一化为0 - 1
.我希望它在同一图形图上,而不是子图上.
I need to plot the first column on X-Axis and rest on Y-Axis.FYI : all the values have been grouped according to X-Axis, the X-Axis values range from 0-25
and all other column values have been normalized to the scale of 0 - 1
. I want it on same graph plot, not subplots.
首选:FactorPlot,法线图.
Preferred : FactorPlot , normal line graph.
推荐答案
df = df.melt('X_Axis', var_name='cols', value_name='vals')
#alternative for pandas < 0.20.0
#df = pd.melt(df, 'X_Axis', var_name='cols', value_name='vals')
g = sns.factorplot(x="X_Axis", y="vals", hue='cols', data=df)
示例:
df = pd.DataFrame({'X_Axis':[1,3,5,7,10,20],
'col_2':[.4,.5,.4,.5,.5,.4],
'col_3':[.7,.8,.9,.4,.2,.3],
'col_4':[.1,.3,.5,.7,.1,.0],
'col_5':[.5,.3,.6,.9,.2,.4]})
print (df)
X_Axis col_2 col_3 col_4 col_5
0 1 0.4 0.7 0.1 0.5
1 3 0.5 0.8 0.3 0.3
2 5 0.4 0.9 0.5 0.6
3 7 0.5 0.4 0.7 0.9
4 10 0.5 0.2 0.1 0.2
5 20 0.4 0.3 0.0 0.4
df = df.melt('X_Axis', var_name='cols', value_name='vals')
g = sns.factorplot(x="X_Axis", y="vals", hue='cols', data=df)
在seaborn的新版本中获得警告:
In new versions of seaborn get warning:
因此,请使用 seaborn.catplot
,如果需要相同的行为,请使用:
So use seaborn.catplot
, if need same behaviour use kind='point'
:
df = df.melt('X_Axis', var_name='cols', value_name='vals')
g = sns.catplot(x="X_Axis", y="vals", hue='cols', data=df, kind='point')
