# 不同文本的布局
|
|
|
|
创建具有不同对齐和旋转的文本。
|
|
|
|
```python
|
|
import matplotlib.pyplot as plt
|
|
import matplotlib.patches as patches
|
|
|
|
# build a rectangle in axes coords
|
|
left, width = .25, .5
|
|
bottom, height = .25, .5
|
|
right = left + width
|
|
top = bottom + height
|
|
|
|
fig = plt.figure()
|
|
ax = fig.add_axes([0,0,1,1])
|
|
|
|
# axes coordinates are 0,0 is bottom left and 1,1 is upper right
|
|
p = patches.Rectangle(
|
|
(left, bottom), width, height,
|
|
fill=False, transform=ax.transAxes, clip_on=False
|
|
)
|
|
|
|
ax.add_patch(p)
|
|
|
|
ax.text(left, bottom, 'left top',

|
|

|
|
|

ax.text(left, 0.5*(bottom+top), 'right center',
|
|
horizontalalignment='right',
|
|
verticalalignment='center',
|
|
rotation='vertical',
|
|

|
|
|

|
|
|
|
ax.text(0.5*(left+right), 0.5*(bottom+top), 'middle',
|
|
horizontalalignment='center',
|
|
verticalalignment='center',
|
|
fontsize=20, color='red',
|
|
transform=ax.transAxes)
|
|
|
|
ax.text(right, 0.5*(bottom+top), 'centered',
|
|
horizontalalignment='center',
|
|
verticalalignment='center',
|
|
rotation='vertical',
|
|
transform=ax.transAxes)
|
|
|
|
ax.text(left, top, 'rotated\nwith newlines',
|
|
horizontalalignment='center',
|
|
verticalalignment='center',
|
|
rotation=45,
|
|
transform=ax.transAxes)
|
|
|
|
ax.set_axis_off()
|
|
plt.show()
|
|
```
