how to set data from server in one field & hard coded data in another field of store

[pawanyanky]

Hi I am developing a chart application in this data is coming from server for both xField and yField of series, but I wanted only yField`s( numeric value e.g. 10, 20, 30, 55, 88 for columns of chart ) data to come from server and make xField ( Jan, Feb, Mar, Apr....Dec ) data to make hard coded in Store. so that application works faster.
I have attached my code in main.txt below, this file has Model, Store, and View of application. and below is my application`s screen shot. on Click of "Change Year" button I am updating store,but I only want to update column field i.e fieldY , not fieldX rounded in red color below, I want fieldX to make hard coded in store. please help me.

If you want a field to have hard coded data that is not returned from the server, you could use the convert config in the field object.

fields : [
    { name : 'foo', convert : function(value, record) { return 'bar'; } }
]

Hi, below is my code for Model and Store , I did as you said but my chart is showing only one column instead of multiple column .

Ext.define("triumphsys/mobility/revenueAnalyzer.model.User", {
extend: "Ext.data.Model",

config: {

/*fields:

[

{name: "name", type: "string"},

{name: "comedy", type: "float"}

]*/

fields :

[

{ name : 'name', convert : function(value, record)

{

var data = [

'Jan',

'Feb',

'Mar',

'Apr',

'May',

'Jun',

'Jul',

'Aug',

'Sep',

'Oct',

'Nov',

'Dec'

];

return data;
}

},

{name: "comedy", type: "float"}

]

}

});

var store = Ext.create("Ext.data.Store", {

model: "triumphsys/mobility/revenueAnalyzer.model.User",

requires: ['Ext.data.Store','Ext.data.proxy.JsonP'],

autoLoad: true,

proxy: {

type: "jsonp",

url : "localhost/mobileApp/sencha-touch/php/getDataForChartDemoMvcViaJsonPFast.php",

callbackKey: 'callback',

reader:

{

type: "json",

rootProperty: "data"

},

success: function(result, request)

{

Ext.Msg.alert(result);

console.log(result);

},

extraParams: {

Year : '2012'

}

}

});

please guide me to solve the issue.
