计算山脊图中每个山脊的样本大小

我希望每个脊上的样本大小文本适用于下面的脊图(可能在右上角)。有没有人用joyplot尝试过。

import joypy

range_P = [0,500,1000,1500,2000,2500,3000]
labels = [('RZ for PRP. \n('+str(range_P[i])+'-'+str(range_P[i]+500)+' mm)') for i in range(7)]

fig, axes = joypy.joyplot([RZS_P['RZ'][(RZS_P['PRP'] > range_P[i]) & (RZS_P['PRP'] <= range_P[i]+500)] for i in range(7)],
                          ylim='own', 
                          overlap = 0, 
                          bins = 20, 
                          figsize=(6,10), 
                          alpha = 0.6, 
                          labels = labels, 
                          color  ='#1f78b4'
                         )
plt.xlim(0,1000)

当Joyplot绘制多个图形时,每个图形的轴都是独立的。因此,您可以设置一个位置并用于循环。

我无法复制您的代码,但是使用了joyplot author's code。文本t1,t2,t3,t4设置在每个图形的右侧。

1。从某处下载iris.csv。

2。设置样本= []。

3。根据需要,通过adjustig y_position = axes[i].get_ylim()[1] / 3.5设置axes []。text(x,y,..)的x和y。

import joypy
import pandas as pd
from matplotlib import pyplot as plt
from matplotlib import cm

iris = pd.read_csv("iris.csv")

sample = ['t1', 't2', 't3', 't4']

%matplotlib inline

fig, axes = joypy.joyplot(iris, ylim='own')

for i in range(len(sample)):
    y_position = axes[i].get_ylim()[1] / 3.5  # adjust with ylim for each plot
    axes[i].text(9, y_position, sample[i])
