layout problem of multiple heatmaps in one figure with matplotlib
0
I put multiple heatmaps in one figure with matplotlib. I cannot layout it well. Here is my code.
import matplotlib; matplotlib.use('agg')
import matplotlib.pyplot as plt
import numpy as np
x = np.random.rand(6,240,240)
y = np.random.rand(6,240,240)
t = np.random.rand(6,240,240)
plt.subplots_adjust(wspace=0.2, hspace=0.3)
c=1
for i in range(6):
ax=plt.subplot(6,3,c)
plt.imshow(x[i])
ax.set_title("x"+str(i))
c+=1
ax=plt.subplot(6,3,c)
plt.imshow(y[i])
ax.set_title("y"+str(i))
c+=1
ax=plt.subplot(6,3,c)
plt.imshow(t[i])
ax.set_title("t"+str(i))
c+=1
plt.tight_layout()
plt.savefig("test.png")
test.png looks like this.
I want to
- make each heatmap bigger
- reduce the margin between each heatmaps in row.
I tried to adjust by "subplots_adjust", but it doesn't work.
Additional information
According to ImportanceOfBeingErnest's comment, I removed tight_layout(). It generated this.
It makes bigger each heatmap, but titles overlappes on subplots. And I still want to make each heatmap more bigger, and I want to reduce the margin in row.

Removeplt.tight_layout()or at least callsubplots_adjustafter that.

Thank you for your advice. I added information above.tight_layout()seems to be needed to prevent overlapping.

Yeah, but now you can play withhspaceand until you're satisfied with the result. Here, probably something likehspace=1or higher is needed. For the spacings in the rows, use higherleftand lowerrightparameter. Most probably you also want to change the figure size.

You should increase the height of the figure.
