Question

import seaborn as sns
import pandas as pd
import matplotlib.pyplot as plt

d = {'x-axis':[100,915,298,299], 'y-axis': [1515,1450,1313,1315],
     'text':['point1','point2','point3','point4']}
df = pd.DataFrame(d)

p1 = sns.relplot(x='x-axis', y='y-axis',data=df )
ax = p1.axes[0,0]
for idx,row in df.iterrows():
    x = row[0]
    y = row[1]
    text = row[2]
    ax.text(x+.05,y,text, horizontalalignment='left')

plt.show()

在此如何确定x轴范围。我的意思是我希望x轴应为0 50 100 150等，我希望yaxis为0 500 1000 1500等，并且还要确保两个轴都从0开始

Answer 1

您可以执行以下操作-使用一行

p1.set(xticks=[i for i in range(0, max(df['x-axis']) + 50, 50)],
       yticks=[i for i in range(0, max(df['y-axis']) + 500, 500)])

动态设置刻度线。

from matplotlib import pyplot as plt
import pandas as pd
import seaborn as sns

d = {'x-axis':[100,915,298,299], 'y-axis': [1515,1450,1313,1315],
     'text':['point1','point2','point3','point4']}
df = pd.DataFrame(d)

p1 = sns.relplot(x='x-axis', y='y-axis',data=df )
ax = p1.axes[0,0]
for idx,row in df.iterrows():
    x = row[0]
    y = row[1]
    text = row[2]
    ax.text(x+.05,y,text, horizontalalignment='left')

p1.set(xticks=[i for i in range(0, max(df['x-axis']) + 50, 50)],
       yticks=[i for i in range(0, max(df['y-axis']) + 500, 500)])


plt.show()

要增加绘图的高度和宽度，以使没有点重叠，只需更改此线即可

p1 = sns.relplot(x='x-axis', y='y-axis', data=df)

到

p1 = sns.relplot(x='x-axis', y='y-axis', data=df, height=10, aspect=1)

您可以根据需要更改height和aspect。

如何在seaborn.relplot中更改轴范围之间的限制
