最基本箱线图

from plotly.offline import plot
import plotly.graph_objs as go 

y = [1140,1460,489,594,502,508,370,200]
trace1 = go.Box(y=y)
layout = go.Layout(plot_bgcolor='#ffffff',width=500,height=500)
data = [trace1]
fig = go.Figure(data=data,layout=layout)
fig.show()

更改一些设置

import plotly.graph_objs as go
import numpy as np 

np.random.seed(10)

c1 = np.random.normal(100,10,200)
c2 = np.random.normal(80,30,200)

trace1 = go.Box(y=c1,fillcolor="#ff7500",marker_color="#ff7500",name="ABC")
trace2 = go.Box(y=c2,fillcolor="#16a951",marker={'color':"#16a951"},name="DEF")

data = [trace1,trace2]

layout = go.Layout(plot_bgcolor='#ffffff',width=500,height=500)

fig = go.Figure(data=data,layout=layout)

fig.show()

遇到一个问题

如何做分组的箱线图

找到分组柱形图的例子

import plotly.graph_objs as go 

x = ["A","B","C"]
y1 = [10,12,14]
y2 = [11,9,20]

trace1 = go.Bar(x=x,y=y1,name='citations',text="kobe")
trace2 = go.Bar(x=x,y=y2,name='teaching',text='Bryant')

data = [trace1,trace2]

layout = go.Layout(barmode="group")

fig = go.Figure(data=data,layout=layout)

fig.show()

模仿柱形图做箱线图

import plotly.graph_objs as go
import numpy as np 

np.random.seed(10)

x1 = ["A"]*200
c1 = np.random.normal(100,10,200)
c2 = np.random.normal(80,30,200)

x2 = ["B"]*200
c3 = np.random.normal(100,10,200)
c4 = np.random.normal(80,30,200)

trace1 = go.Box(x=x1,y=c1,fillcolor="#ff7500",marker_color="#ff7500",name="ABC")
trace2 = go.Box(x=x1,y=c2,fillcolor="#16a951",marker={'color':"#16a951"},name="DEF")

trace3 = go.Box(x=x2,y=c3,fillcolor="#ff7500",marker_color="#ff7500",name="ABC")
trace4 = go.Box(x=x2,y=c4,fillcolor="#16a951",marker={'color':"#16a951"},name="DEF")


data = [trace1,trace2,trace3,trace4]

layout = go.Layout(plot_bgcolor='#ffffff',width=500,height=500,boxmode='group')

fig = go.Figure(data=data,layout=layout)

fig.show()

这个应该不对：
第一个问题是x轴的标签位置是外的，图例应该只有两个。

找到了一个alignmentgroup参数，暂时不知道怎么用！

今天就到这里了

分组的箱线图是这样

import plotly.graph_objs as go
import numpy as np 

np.random.seed(10)

x1 = ["A"]*50
x2 = ["B"]*50
x3 = ["C"]*50
x4 = ["D"]*50
x = x1 + x2 + x3 + x4
print(x)

c1 = np.random.normal(100,10,200)
c2 = np.random.normal(80,30,200)



trace1 = go.Box(x=x,y=c1,fillcolor="#ff7500",marker_color="#ff7500",name="ABC")
trace2 = go.Box(x=x,y=c2,fillcolor="#16a951",marker={'color':"#16a951"},name="DEF")


data = [trace1,trace2]

layout = go.Layout(plot_bgcolor='#ffffff',width=500,height=500,boxmode='group')

fig = go.Figure(data=data,layout=layout)

fig.show()

小提琴图

import plotly.graph_objs as go
import numpy as np 
np.random.seed(10)
x1 = ["A"]*50
x2 = ["B"]*50
x3 = ["C"]*50
x4 = ["D"]*50
x = x1 + x2 + x3 + x4
print(x)
c1 = np.random.normal(100,10,200)
c2 = np.random.normal(80,30,200)
trace1 = go.Violin(x=x,y=c1,fillcolor="#ff7500",marker_color="#ff7500",name="ABC")
trace2 = go.Violin(x=x,y=c2,fillcolor="#16a951",marker={'color':"#16a951"},name="DEF")
data = [trace1,trace2]
layout = go.Layout(plot_bgcolor='#ffffff',width=800,height=500,violinmode='group')
fig = go.Figure(data=data,layout=layout)
fig.show()
