We’ve had a number of requests and suggestions regarding tooltips, so perhaps it would make sense to discuss them in this topic. Currently, the platform supports one global tooltip (which plays nicely with popup menus and mouse hovers), but we are open to extending it if we can find and agree on an intuitive and convenient way for managing sticky tooltips. In any case, even if we do not end up introducing the desired functionality into the core, it should be possible for an application developer to achieve the desired behavior via the Tooltip management API, whatever it is.
Here are few questions to start a discussion:
- How would users make a tooltip sticky on a scatter plot? Not sure if synchronizing it with the selection is a good idea since it’s too easy to select millions of rows, and this will quickly become confusing.
- Should there be a standard way to make any tooltip sticky?
- Should sticky tooltip(s) prevent other tooltips from appearing? Obviously this shouldn’t be the case with the scatter plot.
