@as3script,
I need the same hover effect on Canvas js bar graph.
https://jsfiddle.net/alidingling/30763kr7/
You can achieve this either using stripLines as shown in this JSFiddle or crosshair as shown in this JSFiddle.
-> initially bars will be hidden
-> on hover bars, it will display the hovered bar only.
Please take a look at this JSFiddle.
