Highlight external element on ChartJS hover

Question

I want to be able to generate a chart and when parts of the chart are hovered (i.e. the point on a line graph), I want corresponding elements to have a class added to it on hover. Presumably by passing an array of elements to the hovered data point.

Is this possible in ChartJS? If not, can you recommend a chart software that is capable of this?
