I’m currently building a Vega-Lite chart and one requirement is that it needs to be interactive with the legend as you can see in the images below:
Vega lite bar chart | Vega lite bar chart filtered
The idea is that when I click on a legend item, the values matching in every bar should be filtered out (disappear) instead of being highlighted. I think it should be pretty straightforward but I doubt if it's possible.
Here's the prototype I'm currently building in Vega-Lite Editor
I'm currently using params for creating a binding with the legend and then transform > filter, but the result is that when I click, all the legend items are filtered out except the selected one.
Any idea or suggestion is more than welcome!
