Possible to change chart yField on the fly

[MegaDave1]

I have a linechart based on a store like this.

{period: 1, sales1: 100, sales2: 50},
{period: 2, sales1: 200, sales2: 25},
{period: 3, sales1: 300, sales2: 10}

What I'd like to do is change the yField from sales1 to sales2 on a click event. Is this possible? Do I have to use a different store for each set of data?

I tried but it had no effect on the chart.

Bump.

Is it possible?

Nevermind, found the solution.



var c = Ext.getCmp( 'your_chart_id' );
c.setYField( 'field_name' );
