Re: how to add dual-axis in google chart ?

[asgallant]

Set the series.<series index>.targetAxisIndex option.  Axis index 0 is the left axis, index 1 is the right axis.  Set the axis options using the vAxes.<axis index> options (each takes the same options as are available to vAxis).  Example:

series: {

    0: {

        // use the left axis for the first data series

        targetAxisIndex: 0

    },

    1: {

        // use the right axis for the second data series

        targetAxisIndex: 1

    }

},

vAxes: {

    0: {

        title: 'Left Axis'

    }

    1: {

        title: 'Right Axis'

    }

}

How do you implement this?? 

I am learning javascript to use these charts. I just need sort of a code example. I need dual-axis and this is the only example I have found of this.
