Dynamically Changing the yField possible?

[jcorredor]

I'm trying to make the data change in my line graph dynamically. I have it all under one store, where each year is a field as well as one field for the name of the category like so...

fields: ['name', '2000', '2001', '2002', '2003', '2004', '2005', '2006', '2007', '2008', '2009', '2010', '2011', '2012'],

each field will have different categories, so '2000', for example, will contain a value for say 'water', 'land', 'air'.

in my line graph..

var date = 2000;

...

changeDate: function(newDate) {
        date = newDate;

in the series field..

yField: [date]

This seems to work for the first value I give to date, however, every time I call changeDate, the graph does not update with the new yField. Is there anything I have to do to refresh the graph so that it accepts a new value for the yField? Or is the yField a set value that does not change after the graph is rendered? I have tried redraw(), but the graph does not change.

side note: This is similar to what EnergyChart does with the year graph. However, they change the content of their store every time. Is this the only solution to dynamic graphing?

No, you will need to create a new chart if you want to change the yField.
