I have built a changelog viewer and want to know if it was possible to change the behavior when a user click on a mark. Instead of selecting it I would like to show the data behind.
If possible, would be great if I could still drag over a range of marks to select them.
I havent done that myself but i assume its possible.
Try playing with the tooltips, they activate on hover. If you make a non-static parameter be the tooltip, it will change based on selection.
