HoverData doesnt work on smartphones?


I refresh a pie graph using a hoverData (from a barchart) as input. When the mouse is on a bar, the piechart is refreshed, with the hover x value as input. On desktop, there is no problem.

But when displaying the same graph on a smartphone, the piecharts are not refreshed anymore; it looks like the “hoverData” stays empty, because there is no mouse anymore?

Still, “touching” on a bar, Dash displays the name, the hoverinfo, and text. Which means that somewhere, somehow, Dash is perfectly able to know where the “touch” is. Then, why doesn’t it refresh the Piechart, when the screen is touched ??
