Hello, I have created the following graph using fig.add_layout_image
fig.add_layout_image doesn’t have hovertext parameters like most of the other plotly graph objects. Is there some other way to add this? I believe I want this more customizable than anything I can load into the layout since it won’t be the plotted values.
Hey @marketemp,
Here’s my idea:
You can add dummy trace with hovertext and set opacity zero to make it invisible.
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(go.Scatter(x=[1,20,30],
y=[1,25,35],
mode="markers")
)
#Dummy Rectangle -> opacity = 0 (invisible)
fig.add_trace(
go.Scatter(
x=[10,10,15,15,10], #x1-x1-x2-x2-x1
y=[15,20,20,15,15], #y1-y2-y2-y1-y1
fill="toself",
mode='lines',
name='',
text='Custom text on top of shape',
opacity=0
)
)
## Add image
fig.add_layout_image(
dict(
source="https://raw.githubusercontent.com/cldougl/plot_images/add_r_img/vox.png",
xref="x", yref="y", # reference to axis not to paper
x=10, y=20, # position
sizex=5, sizey=5, # size
)
)
# update layout properties
fig.update_layout(
height=800,
width=800)
fig.show()```I have about five hundred images and have already spent many hours modifying them from a white background (each look like white squares and block each other out) to a neutral background.
Definitely is no good idea if you have to manually edit many images. I happy to see, that @akroma was able to help you.
