base: master
Are you sure you want to change the base?
Conversation
Implemented style and template handling
I figured it out. |
Apologies @kb- - we are trying to get the next Dash and Plotly.py releases out the door, so we're short on cycles for reviewing PRs (particularly ones that touch this many files). I'll try to prioritize it in the next work cycle, but realistically it's going to be at least a couple more weeks :-( Thanks for your patience - @gvwilson |
This PR addresses #7054
The tooltip function can be activated by a new modebar button.
It allows to add an annotation to every clicked point. By default, tooltips contain x, y and when available z, or ohlc data (open, high, low, close).
Tooltips can be customized with an optional tooltiptemplate (leverages existing hovertemplate code) and tooltip annotation options (leverages existing annotations code)

I added examples for various plot types in \test\image\mocks
Additional interactivity:
When a plot is created with
editable: true
, the tooltips can be dragged around for placement or deleted interactively. Their text can also be edited. To delete a tooltip, click on its text and delete it.Compatibility:
(active for plots with hasCartesian or hasGL2D)
