我希望水平调整子图之间的空间。特别是在第二行之间。我可以使用fig.subplots_adjust(hspace=n)
调整每一行。但是可以将其应用于第二行吗?
import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize = (10,10))
plt.style.use('ggplot')
ax.grid(False)
ax1 = plt.subplot2grid((5,2), (0, 0))
ax2 = plt.subplot2grid((5,2), (0, 1))
ax3 = plt.subplot2grid((5,2), (1, 0))
ax4 = plt.subplot2grid((5,2), (1, 1))
ax5 = plt.subplot2grid((5,2), (2, 0))
ax6 = plt.subplot2grid((5,2), (2, 1))
ax7 = plt.subplot2grid((5,2), (3, 0))
ax8 = plt.subplot2grid((5,2), (3, 1))
fig.subplots_adjust(hspace=0.9)

在不进行诸如手动调整轴位置之类的繁琐的低级黑客攻击的情况下,我建议使用网格,但只需将某些行留空。
我尝试过:
import matplotlib.pyplot as plt
plt.figure(figsize=(10., 10.))
num_rows = 6
num_cols = 2
row_height = 3
space_height = 2
num_sep_rows = lambda x: int((x-1)/2)
grid = (row_height*num_rows + space_height*num_sep_rows(num_rows), num_cols)
ax_list = []
for ind_row in range(num_rows):
for ind_col in range(num_cols):
grid_row = row_height*ind_row + space_height*num_sep_rows(ind_row+1)
grid_col = ind_col
ax_list += [plt.subplot2grid(grid, (grid_row, grid_col), rowspan=row_height)]
plt.subplots_adjust(bottom=.05, top=.95, hspace=.1)
# plot stuff
ax_list[0].plot([0, 1])
ax_list[1].plot([1, 0])
# ...
ax_list[11].plot([0, 1, 4], c='C2')
给出以下结果:
请注意,您可以更改行数。另外,您可以通过调整row_height
/ space_height
的比例(两者都必须是整数)来调整与子图相比的空白大小。

您可以交错两个网格,以使第二个子图之间有更大的间距。
为了说明这个概念:
import matplotlib.pyplot as plt
from matplotlib.gridspec import GridSpec
n = 3 # number of double-rows
m = 2 # number of columns
t = 0.9 # 1-t == top space
b = 0.1 # bottom space (both in figure coordinates)
msp = 0.1 # minor spacing
sp = 0.5 # major spacing
offs=(1+msp)*(t-b)/(2*n+n*msp+(n-1)*sp) # grid offset
hspace = sp+msp+1 #height space per grid
gso = GridSpec(n,m, bottom=b+offs, top=t, hspace=hspace)
gse = GridSpec(n,m, bottom=b, top=t-offs, hspace=hspace)
fig = plt.figure()
axes = []
for i in range(n*m):
axes.append(fig.add_subplot(gso[i]))
axes.append(fig.add_subplot(gse[i]))
plt.show()
