1. 格式化不等宽子图
fig.add_gridspec(行数，列数，宽度比，长度比，坐标x，坐标y，子图宽度，子图高度，子图水平间距，子图竖直间距)
gs = fig.add_gridspec(2, 2, width_ratios=(7, 2), height_ratios=(2, 7),
left=0.1, right=0.9, bottom=0.1, top=0.9
# ,wspace=0.05, hspace=0.05)
添加不等宽子图
ax = fig.add_subplot(gs[1, 0])
ax_histx = fig.add_subplot(gs[0, 0], sharex=ax)
ax_histy = fig.add_subplot(gs[1, 1], sharey=ax)
sharex=ax——共享x轴
sharey=ax——共享y轴
子图：与列表索引相同，含义如上图
Example 1
from __future__ import print_function, divisionimport numpy as npimport matplotlib as mplimport matplotlib.pyplot as plt%matplotlib inline# start with a square Figurefig = plt.figure(figsize=(8, 8)) # Add a gridspec with two rows and two columns and a ratio of 2 to 7 between# the size of the marginal axes and the main axes in both directions.# Also adjust the subplot parameters for a square plot.gs = fig.add_gridspec(2, 2, width_ratios=(7, 2), height_ratios=(2, 7), left=0.1, right=0.9, bottom=0.1, top=0.9# ,wspace=0.05, hspace=0.05 ) ax = fig.add_subplot(gs[1, 0])ax_histx = fig.add_subplot(gs[0, 0], sharex=ax)ax_histy = fig.add_subplot(gs[1, 1], sharey=ax) # use the previously defined function# scatter_hist(x, y, ax, ax_histx, ax_histy) plt.show()
Example 2
import matplotlib.pyplot as pltfrom matplotlib.gridspec import GridSpec
def format_axes(fig): for i, ax in enumerate(fig.axes): ax.text(0.5, 0.5, "ax%d" % (i+1), va="center", ha="center") ax.tick_params(labelbottom=False, labelleft=False)
fig = plt.figure(constrained_layout=True)
gs = GridSpec(2,2, figure=fig)ax1 = fig.add_subplot(gs[0,0])# identical to ax1 = plt.subplot(gs.new_subplotspec((0, 0), colspan=3))ax2 = fig.add_subplot(gs[1,0])ax3 = fig.add_subplot(gs[:,1])# ax4 = fig.add_subplot(gs[-1, 0])# ax5 = fig.add_subplot(gs[-1, -2])
fig.suptitle("GridSpec")format_axes(fig)
plt.show()
2. 任意位置，任意尺寸
fig.add_axes([坐标x，坐标y，子图宽度，子图高度])
axes = fig.add_axes([0.2, 0.2, 0.3, 0.3])
内参——列表：# left, bottom, width, height (range 0 to 1)
axes2 = fig.add_axes([0.4, 0.6, 0.3, 0.3]) # inset axes
%matplotlib autoimport matplotlib.pyplot as pltfrom pylab import *x = linspace(0, 5, 10)y = x ** 2
fig = plt.figure()
axes = fig.add_axes([0.2, 0.2, 0.3, 0.3]) # left, bottom, width, height (range 0 to 1)axes2 = fig.add_axes([0.4, 0.6, 0.3, 0.3]) # inset axes
axes.plot(x, y, 'r')
axes.set_xlabel('x')axes.set_ylabel('y')axes.set_title('title')
# insertaxes2.plot(y, x, 'g')axes2.set_xlabel('y')axes2.set_ylabel('x')axes2.set_title('insert title');
plt.show()
