From this answer我知道如何绘制显示数组值的图像。 但是如何显示数组中每个元素的OpenBrowser
索引,而不是值本身?
这是在图像中打印值的方式:
i,j
现在,如何在左上角from matplotlib import pyplot
import numpy as np
grid = np.array([[1,8,13,29,17,26,10,4],[16,25,31,5,21,30,19,15]])
fig1, (ax1, ax2)= pyplot.subplots(2, sharex = True, sharey = False)
ax1.imshow(grid, interpolation ='none', aspect = 'auto')
ax2.imshow(grid, interpolation ='bicubic', aspect = 'auto')
for (j,i),label in np.ndenumerate(grid):
ax1.text(i,j,label,ha='center',va='center')
ax2.text(i,j,label,ha='center',va='center')
pyplot.show()
制作imshow
而非价值(0,0)
?
1
答案 0 :(得分:1)
如何在左上角制作imshow plot(0,0)而不是值1?
这个问题的天真答案是text(i,j,'(0,0)', ...
,它将(0,0)
放在每个元素上。
我想这就是你真正想要的:
from matplotlib import pyplot
import numpy as np
grid = np.array([[1,8,13,29,17,26,10,4],[16,25,31,5,21,30,19,15]])
fig1, (ax1, ax2)= pyplot.subplots(2, sharex = True, sharey = False)
ax1.imshow(grid, interpolation ='none', aspect = 'auto')
ax2.imshow(grid, interpolation ='bicubic', aspect = 'auto')
for (j, i), _ in np.ndenumerate(grid):
label = '({},{})'.format(j, i)
ax1.text(i,j,label,ha='center',va='center')
ax2.text(i,j,label,ha='center',va='center')
pyplot.show()
