2 – For bar chart, x-axis mode (thanks for this option @Mesonyx) depends of “stacked” param
if stacked is true, mode = label
if stacked is false, mode = single
So i’m wondering if “x-axis” shouldn’t be an option instead of a “mode”. It will give the liberty to have x-axis + single or x-axis + label.
3 – For line chart, when pointRadius = 0 (for a clean design or when there is a lot of data points) tooltip is visible only if your cursor is on the 1px corresponding to the X.
It is possible to have something like padding left/right = space between two points / 2 for the “hover zone” of the tooltip.
