python画柱形图把奇数年份也显示出来_python - Matplotlib奇数子图 - 堆栈内存溢出...

我必须绘制一个有11个子点的图，如下所示。 但由于它是一个奇数，我不知道如何处理子图（4,3,12）去除它...并将2个最后的图放在中心而且我想增加子图大小作为空间太重要了。 代码如下。

代码是：

plt.close()

fig, axes = plt.subplots(nrows=4, ncols=3)

plt.tight_layout(pad=0.05, w_pad=0.001, h_pad=2.0)

ax1 = plt.subplot(431) # creates first axis

ax1.set_xticks([])

ax1.set_yticks([])

ax1.tick_params(labelsize=8)

i1 = ax1.imshow(IIIm,cmap='hot',extent=(0,2000,0,2000),vmin=-0.2,vmax=-0.1)

i11 = ax1.plot((0,600),(1000,1000),'k-',linewidth=3)

cb1=plt.colorbar(i1,ax=ax1,ticks=[-0.2,-0.15,-0.1],fraction=0.046, pad=0.04,format='%.3f')
