How to change highlighted color (pink) of the bar?

[Roman Nachankin]

For one of the chart I would like to disable mouseover highlighing of the bar. So If you move a mouse over the bar, the color should stay the same.

Default behaviour the bar get class "hover" and the pink color.

If it is possible, is there any option for that?

I am using the bar options as a JSON object, like

options: {
type: 'multiBarChart',
height: 450,
margin : { top: 20, right: 20, bottom: 50, left: 70 },
stacked: true,
reduceXTicks: false, 

...

}

thanks and best regards
