[英]Plot graph with multiple attributes similar to “hue” in Seaborn
我有以下示例数据集,名为df
,其中舞台时间是到达df
天数:
id stage1_time stage_1_to_2_time stage_2_time stage_2_to_3_time stage3_time
a 10 30 40 30 70
b 30
c 15 30 45
d
我编写了以下脚本来获取stage1_time
对CDF的散点图:
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
import scipy.stats as stats
dict = {'id': id, 'stage_1_time': [10, 30, 15, None], 'stage_1_to_2_time': [30, None, 30, None], 'stage_2_time' : [40, None, 45, None],'stage_2_to_3_time' : [30, None, None, None],'stage_3_time' : [70, None, None, None]}
df = pd.DataFrame(dict)
#create eCDF function
def ecdf(df):
n = len(df)
x = np.sort(df)
y = np.arange(1.0, n+1) / n
return x, y
def generate_scatter_plot(df):
x, y = ecdf(df)
plt.plot(x, y, marker='.', linestyle='none')
plt.axvline(x.mean(), color='gray', linestyle='dashed', linewidth=2) #Add mean
x_m = int(x.mean())
y_m = stats.percentileofscore(df.as_matrix(), x.mean())/100.0
plt.annotate('(%s,%s)' % (x_m,int(y_m*100)) , xy=(x_m,y_m), xytext=(10,-5), textcoords='offset points')
percentiles= np.array([0,25,50,75,100])
x_p = np.percentile(df, percentiles)
y_p = percentiles/100.0
plt.plot(x_p, y_p, marker='D', color='red', linestyle='none') # Overlay quartiles
for x,y in zip(x_p, y_p):
plt.annotate('%s' % int(x), xy=(x,y), xytext=(10,-5), textcoords='offset points')
#Data to plot
stage1_time = df['stage_1_time'].dropna().sort_values()
#Scatter Plot
stage1_time_scatter = generate_scatter_plot(pd.DataFrame({"df" : stage1_time.as_matrix()}))
plt.title('Scatter Plot of Days to Stage1')
plt.xlabel('Days to Stage1')
plt.ylabel('Cumulative Probability')
plt.legend(('Days to Stage1', "Mean", 'Quartiles'), loc='lower right')
plt.margins(0.02)
plt.show()
输出:
目前,所有达到stage1
根据其累积概率绘制的天数,但是我想要实现的是当我绘制时散布有三种颜色:那些到达stage1
并留在那里的人,那些进入stage2
和那些谁转移到stage3
。 我也想在图表中的数据计数:#在stage1
中,# stage2
中和# stage3
。
有人可以帮忙到那里吗?
仅供参考,意图是使用它作为基础,这样我也可以为stage2_time
创建一个图形,其中到达stage_3
的图形突出显示不同的颜色。
您可以创建一个新列并使用它来存储最终阶段,然后使用此新列为您的绘图着色。
