有没有办法使用Seaborn的Pairplot强制进行科学计数?我希望图之间保持一定的一致性(下面的示例)。我已经找到了其他海底图的建议,但是还没有使用Pairplot成功实现任何东西。

版本:
海上0.8.1
numpy的1.13.1
matplotlib 2.0.2
熊猫0.23.0
当前情节:
import numpy as np
import pandas as pd
import seaborn as sns
from scipy import stats
import matplotlib.pyplot as plt
#remove NAs
dfna = df.dropna()
#Correlation function
mean = np.zeros(3)
cov = np.random.uniform(.2, .4, (3, 3))
cov += cov.T
cov[np.diag_indices(3)] = 1
def corrfunc(x, y, **kws):
r, _ = stats.pearsonr(x, y)
ax = plt.gca()
ax.annotate("{:.2f}".format(r),
xy=(.3, .45), xycoords=ax.transAxes, fontsize = 30)
#2D regression + distribution
p = sns.pairplot(dfna, diag_kind="kde", diag_kws=dict(shade=True, color = "Blue"), plot_kws=dict(s=5, edgecolor="Blue", color = "Blue", linewidth=1))
p.fig.text(0.5, 1.00,'BLAHH', fontsize=30)
p.map_upper(plt.scatter, color = "White", edgecolor = "White")
p.map_upper(corrfunc)
p.fig.text(0.35, -0.04, "xxx", ha ='left', fontsize = 20)
p.fig.text(-0.04, 0.68, "xxx", ha ='left', fontsize = 20, rotation = 90)
#p.savefig('pairplot.svg')
重新格式化的尝试失败:
plt.ticklabel_format(style = 'sci')
import matplotlib.ticker as tkr
formatter = tkr.ScalarFormatter(useMathText=True)
formatter.set_scientific(True)
p = sns.pairplot(dfna, plot_kws = {'format': formatter})

最佳答案
您需要将格式化程序应用于pairplot
创建的每个轴。实际上,边缘上的轴就足够了,但是将相同的事物平均应用于所有轴会更容易。我会做:
for ax in g.axes.flatten():
ax.ticklabel_format(style='sci', scilimits=(0,0), axis='both')
