How to disable hover property on waterfall charts.

[How to disable hover property on waterfall charts.]

Hi,

I am new to fusion chart. I am using waterfall chart for data representation.

 

Here I am trying to disable hover property of chart. I mean -"If the mouse pointer is on some column in the chart it should not hover".

I am using following setting-

chart  : {

................   .......

"showHoverEffect" : "0",
"plotHoverEffect" : "0"
} 

But it does not disable hovering property.

Please help!
