matplotlib画图-子图设置

画了一堆子图，发现 figsize=size、plt.subplots_adjust、plt.tight_layout之间有冲突，测试完，在来补充

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
%matplotlib inline
plt.rcParams['font.sans-serif']=['SimHei']
plt.rcParams['axes.unicode_minus']=False

#特征频数统计
lt = []
for col in data.columns[1:]:
    lt.append(data.groupby(col).size())
nrow, ncol = 6, 3
size = (4.5*ncol, 10*nrow)
fig, ax = plt.subplots(nrow, ncol, figsize=size) 
n = 0
x_major_locator=MultipleLocator(1) 主刻度是1的倍数
for c in range(ncol):
    for r in range(nrow):
        ct = lt[n]
        ax[r, c].bar(ct.index, ct.values)        
        ax[r, c].set_title(data.columns[n+1])
        ax[r, c].xaxis.set_major_locator(x_major_locator)   #把x轴的主刻度设置为1的倍数
        n += 1   
plt.subplots_adjust(wspace=0.1, hspace=0.5)
plt.tight_layout(pad=5,h_pad=12)
plt.show()
