Seaborn中没有线性拟合的散点图 [英] Scatterplot without linear fit in seaborn

问题描述

我想知道是否有一种方法可以关闭seaborn的 lmplot 中的线性拟合，或者是否有一个等效函数只是生成散点图.当然，我也可以使用matplotlib，但是，我发现seaborn的语法和美学非常吸引人.例如，.我想绘制以下情节

I am wondering if there is a way to turn off the linear fit in seaborn's lmplot or if there is an equivalent function that just produces the scatterplot. Sure, I could also use matplotlib, however, I find the syntax and aesthetics in seaborn quite appealing. E.g,. I want to plot the following plot

import seaborn as sns
sns.set(style="ticks")

df = sns.load_dataset("anscombe")
sns.lmplot("x", "y", data=df, hue='dataset')

没有像这样的线性拟合:

Without the linear fit like so:

from itertools import cycle
import numpy as np

import matplotlib.pyplot as plt

color_gen = cycle(('blue', 'lightgreen', 'red', 'purple', 'gray', 'cyan'))

for lab in np.unique(df['dataset']):
    plt.scatter(df.loc[df['dataset'] == lab, 'x'], 
                df.loc[df['dataset'] == lab, 'y'], 
                c=next(color_gen),
                label=lab)

plt.legend(loc='best')

推荐答案

set fit_reg 参数为 False:

sns.lmplot("x", "y", data=df, hue='dataset', fit_reg=False)
