I'm trying to plot multiple heatmaps using the plt.subplots
. An example I found is as follows:
import numpy as np
import matplotlib.pyplot as plt
# Generate some data that where each slice has a different range
# (The overall range is from 0 to 2)
data = np.random.random((4,10,10))
data *= np.array([0.5, 1.0, 1.5, 2.0])[:,None,None]
# Plot each slice as an independent subplot
fig, axes = plt.subplots(nrows=1, ncols=4,figsize=(12,3))
i=0
for dat, ax in zip(data, axes.flat):
# The vmin and vmax arguments specify the color limits
im = ax.imshow(dat, vmin=0, vmax=2,cmap='Reds')
# ax.xlabel(str(i))
# ax.ylabel(str(i))
i += 1
# Make an axis for the colorbar on the right side
cax = fig.add_axes([0.95, 0.155, 0.03, 0.67])
fig.colorbar(im, cax=cax)
figtype = 'jpg'
fig.savefig('aaa.jpg',format = figtype,bbox_inches='tight')
fig.tight_layout()
The code succeeds if I comment the following two lines (which is done in the above example):
ax.xlabel(str(i))
ax.ylabel(str(i))
If I use the two lines, I get errors saying:
AttributeError: 'AxesSubplot' object has no attribute 'xlabel'
How can I make it correct?
Thank you all for helping me!!!
