The documents say it does not for all images. But I saw hover tool now works with image. My question is, Is it working with image_url? Thanks.
That list is out of date. Hover is supported for Image
and ImageRGBA
:
But is not supported for ImageURL
Note that if it ever is aded for ImageURL
it would be at best a single “hit” just like with a scatter marker. It would not be the per-pixel hit testing that Image
and ImageRGBA
can offer (because there is no backing data source with per-pixel data to interrogate).
EDIT: I’ve made a PR to update the docstring here: Update out of date HoverTool docstring by bryevdv · Pull Request #10357 · bokeh/bokeh · GitHub
