Chart.js multiple dataset issue: hovering over n-th point "hovers" over every dataset's n-th point

Question

Example situation: I have 2 line datasets in one chart.

if I hover over the second dataset's second point, it also detects hover at every other dataset's second point.

You need to set chart's hover mode to 'nearest', in your chart options config, like so :

options: {
      hover: {
         mode: 'nearest'
      },
      ...

this will ensure that only the hovered data-point gets active.
