[英]How to add titles to subplots containing images
Starting from a basic image example , I made 3 subplots:从一个基本的图像示例开始,我制作了 3 个子图:
import plotly.graph_objects as go
from plotly.subplots import make_subplots
imgs_rgb = (
[[[255, 0, 0], [0, 255, 0], [0, 0, 255]],
[[0, 255, 0], [0, 0, 255], [255, 0, 0]]],
[[[255, 127, 0], [127, 255, 0], [127, 0, 255]],
[[127, 255, 0], [127, 0, 255], [255, 127, 0]]],
[[[0, 255, 255], [0, 255, 127], [255, 0, 255]],
[[255, 255, 0], [0, 255, 255], [127, 255, 0]]],
)
fig = make_subplots(rows=len(imgs_rgb), cols=1)
for row, img_rgb in enumerate(imgs_rgb):
fig.add_trace(
go.Image(z=img_rgb),
row=row+1,
col=1
)
fig.show()
How can we add a title/label to each individual subplot, as shown eg here: https://plotly.com/python/imshow/#exploring-3d-images-timeseries-and-sequences-of-images-with-facetcol我们如何为每个单独的子图添加标题/标签,如下所示: https ://plotly.com/python/imshow/#exploring-3d-images-timeseries-and-sequences-of-images-with-facetcol
Note that I don't have plotly.express
, so using its functionality isn't an option.请注意,我没有plotly.express
,因此不能选择使用它的功能。
You can just a pass the subplot titles when calling make_subplots()
:您可以在调用make_subplots()
时传递子图标题:
import plotly.graph_objects as go
from plotly.subplots import make_subplots
imgs_rgb = (
[[[255, 0, 0], [0, 255, 0], [0, 0, 255]],
[[0, 255, 0], [0, 0, 255], [255, 0, 0]]],
[[[255, 127, 0], [127, 255, 0], [127, 0, 255]],
[[127, 255, 0], [127, 0, 255], [255, 127, 0]]],
[[[0, 255, 255], [0, 255, 127], [255, 0, 255]],
[[255, 255, 0], [0, 255, 255], [127, 255, 0]]],
)
fig = make_subplots(rows=len(imgs_rgb), cols=1, subplot_titles=("Plot1", "Plot2", "Plot3"))
for row, img_rgb in enumerate(imgs_rgb):
fig.add_trace(
go.Image(z=img_rgb),
row=row+1,
col=1
)
fig.show()
