Extjs chart picking wrong Store?

I am trying to draw two charts side by side which will use same store by passing different parameters but both charts are using second store's value. I can see response in Chrome console, it is proper with two requests and different response; below is my code.
Ext.define('testUtility.view.BarChart', {
extend: 'Ext.chart.Chart',
alias: 'widget.barChart',
renderTo: Ext.getBody(),
store: Ext.create('Ext.data.Store', {
fields: ['name', 'data'],
autoLoad: false,
proxy: {
type: 'ajax',
url: 'data/store1',
reader: {
type: 'json',
root: 'Data'
},
filterParam: undefined,
groupParam: undefined,
pageParam: undefined,
startParam: undefined,
sortParam: undefined,
limitParam: undefined
}
}),
axes: [{
type: 'Numeric',
position: 'left',
fields: ['data'],
label: {
renderer: Ext.util.Format.numberRenderer('0,0')
},
title: 'Values',
grid: true,
minimum: 0
}, {
type: 'Category',
position: 'bottom',
fields: ['name'],
title: 'Master'
}],
series: [{
type: 'column',
axis: 'left',
highlight: true,
tips: {
trackMouse: true,
width: 100,
height: 28,
renderer: function(storeItem, item) {
this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data') + ' $');
}
},
label: {
display: 'insideEnd',
'text-anchor': 'middle',
field: 'data',
renderer: Ext.util.Format.numberRenderer('0'),
orientation: 'vertical',
color: '#333'
},
xField: 'name',
yField: 'data'
}]
});
app.js
Ext.application({
requires: [
'Ext.container.Viewport'
],
name: 'BAR Chart ',
launch: function() {
var chart1 = Ext.create('testUtility.view.BarChart', {
id: 'chart1',
height: 300,
width: '50%'
});
var store1 = chart1.getStore();
store1.proxy.extraParams = {
id: chart1.id
};
store1.load();
var chart2 = Ext.create('testUtility.view.BarChart', {
id: 'chart2',
height: 300,
width: '50%'
});
var store2 = chart2.getStore();
store2.proxy.extraParams = {
id: chart2.id
};
store2.load();
}
});
Both charts shows data from store whichever is loaded later.

Both of your stores are one and the same, when you call them in your definition. You should call the store when creating the instance of the class like so:
var chart1 = Ext.create( 'testUtility.view.BarChart', {
id: 'chart1',
height: 300,
width: '50%',
store: store1
} );
It is good practice to define your own store:
Ext.define( 'testUtility.store.BarChart', {
extend: 'Ext.data.Store',
...
} );
And then just use it before the first part of the code:
var store1 = Ext.create( 'testUtility.store.BarChart', { options } );
Your options including the extraparams, different for the 2 stores.

Rendering pie chart using xtype and Ext.create

I first tried to render a pie chart using xtype into centre region of a panel with border layout. Here is the code:
{
xtype:'pie',
renderTo: Ext.getBody(),
width: 200,
height: 150,
animate: true,
layout:'fit',
store: store,
theme: 'Base:gradients',
series: [{
type: 'pie',
field: 'salary',
showInLegend: true,
highlight: {
segment: {
margin: 20
}
},
label: {
field: 'name',
display: 'rotate',
contrast: true,
font: '18px Arial'
}
}]
}
I am getting the following error:
Uncaught TypeError: Cannot call method 'substring' of undefined
But when i take the same code and use Ext.create then it is working fine.
var chart=Ext.create('Ext.chart.Chart', {
renderTo: Ext.getBody(),
width: 200,
height: 150,
animate: true,
layout:'fit',
store: store,
theme: 'Base:gradients',
series: [{
type: 'pie',
field: 'salary',
showInLegend: true,
highlight: {
segment: {
margin: 20
}
},
label: {
field: 'name',
display: 'rotate',
contrast: true,
font: '18px Arial'
}
}]
});
I am using chart as an item instead.
What can be the problem?
Here is the store:
var store=Ext.create('Ext.data.Store',{
model:'Layouts.Person',
autoLoad:true,
data:{'items':[
{'name':'john','empno':'1111','salary':'1234'},
{'name':'edward','empno':'1212','salary':'2234'},
{'name':'frank','empno':'1567','salary':'9774'},
{'name':'michel','empno':'3456','salary':'8932'},
]},
proxy:{
type:'memory',
reader:{
type:'json',
root:'items'
}
}
});
The xtype for pie chart is pie:
http://www.objis.com/formationextjs/lib/extjs-4.0.0/docs/api/Ext.chart.series.Pie.html

try this code it will work out for you.
{
xtype:'chart',
animate: true,
width: 500,
height: 300,
store: store,
theme: 'Base:gradients',
series: [{
type: 'pie',
field: 'data1',
showInLegend: true,
tips: {
trackMouse: true,
width: 140,
height: 28,
renderer: function(storeItem, item) {
//calculate and display percentage on hover
var total = 0;
store.each(function(rec) {
total += rec.get('data1');
});
this.setTitle(storeItem.get('name') + ': ' + Math.round(storeItem.get('data1') / total * 100) + '%');
}
},
highlight: {
segment: {
margin: 20
}
},
label: {
field: 'name',
display: 'rotate',
contrast: true,
font: '18px Arial'
}
}]
}

EXTJS4: App is not loading when TreeView is embed

My App works fine, if the TreeView "TreeCreateMenu" is not embed. Since it is embed, the app stocks at the Browser-Web-Console at the Point from the extjs-directory "Trigger.js". But no error is displayed!
Here are my files:
The Viewport:
Ext.define('App.view.Viewport', {
extend: 'Ext.container.Viewport',
requires: [
'App.view.Settings',
'App.view.Footer',
'App.view.TreeMenu',
'App.view.tree.TreeCreateMenu',
],
layout: 'border',
items: [
{
region: 'north',
border: false,
margin: '0 0 1 0',
split: true,
items: [{xtype: 'settings'}]
}, {
region: 'west',
collapsible: true,
title: 'Menu',
width: 250,
layout: 'vbox',
items: [
{
xtype: 'treemenu',
height: 600,
minSize: 600,
maxSize: 600,
layout: 'fit',
flex: 1
},
{
title: 'Create',
layout: 'fit',
border: '1 0 0 0',
width: 250,
height: 100,
items: [{xtype: 'treecreatemenu'}]
}
]
// could use a TreePanel or AccordionLayout for navigational items
}, {
region: 'south',
layout: 'fit',
height: 20,
items: [{xtype: 'footertoolbar'}]
}, {
region: 'center',
id:'region_center',
layout: 'fit',
border: '1 0 0 0',
items: []
}
],
initComponent: function() {
this.callParent();
}
});
The Controller of TreeCreateMenu
Ext.define('App.controller.tree.TreeCreateMenu', {
extend: 'Ext.app.Controller',
views: ['tree.TreeCreateMenu'],
models: ['tree.TreeCreateMenu'],
stores: ['tree.TreeCreateMenu'],
onLaunch: function() {},
refs: [{
selector: 'tree',
ref: 'treecreatemenu'
}],
init: function() {
this.control({
'treecreatemenu': {
itemclick: function(view, node, rec, item, index, e ) {}
}
});
}
});
The model:
Ext.define('App.model.tree.TreeCreateMenu', {
extend: 'Ext.data.Model',
displayField: 'text',
fields: [
{name: 'text', type: 'string', leaf:false},
{name: 'value', type: 'string', leaf:false},
]
});
The store: (Response is correct, because i displayed it at the TreeMenu.js in the Viwport)
Ext.define('App.store.tree.TreeCreateMenu', {
extend: 'Ext.data.TreeStore',
requires: 'App.model.tree.TreeCreateMenu',
model: 'App.model.tree.TreeCreateMenu',
AutoLoad: false,
nodeParam: 'value',
proxy: {
type: 'ajax',
url: 'bin/app/ajax.php',
extraParams: {
action:'getTreeCreateMenu'
},
reader: {
type: 'json',
root: 'children'
},
actionMethods: {
create : 'POST',
read : 'POST',
update : 'POST',
destroy: 'POST'
}
}
});
And my View:
Ext.define('App.view.tree.TreeCreateMenu', {
extend: 'Ext.tree.Panel',
alias: 'widget.treecreatemenu',
//store: 'tree.TreeCreateMenu',
rootVisible: false,
bodyStyle: 'border:none;',
padding:'5,0,0,0'
});
So nothing special...but it doesn't work and I have absolutely no idea! Someone can help me with this please? THANKS!!

How to show grid in window with ExtJs?

Thare is problem in my ExtJs app.
I want to show grid in window. I says:
Column Model:
var markCm = new Ext.grid.ColumnModel({
columns:[{
header: 'Аннотация',
dataIndex: 'annotation',
width: 230,
},{
header: 'Дата',
dataIndex: 'mark_date',
width: 30
},{
header: 'Статус',
dataIndex: 'status',
width: 30
}],
defaults: {
flex: 1
}
});
console.log("1");
Grid:
var markGrid = new Ext.grid.GridPanel({
//store: markStore,
cm: markCm,
selModel: new Ext.grid.RowSelectionModel(),
stripeRows : true,
//height: 400,
//loadMask: true,
id: 'markGrid',
autoScroll: true,
});
Window:
console.log("2");
var markWin = new Ext.Window({
id: 'markWindow',
layout: 'fit',
title:'Спискок маркеров',
autoScroll:false,
//width:600,
items:[markGrid],
listeners:{
}
});
console.log("3");
markWin.show();
console.log("4");
And in firebug i see:
1
2
3
TypeError: this.ds is undefined
...ng(this.enableUrlEncode)?this.enableUrlEncode:"data"]=Ext.encode(h);k.params=l}e...
Whats can be wrong?
UPDATE
I try add store like in this example
var markGrid = new Ext.grid.GridPanel({
store: Ext.create('Ext.data.ArrayStore', {}),
cm: markCm,
selModel: new Ext.grid.RowSelectionModel(),
stripeRows : true,
//height: 400,
//loadMask: true,
id: 'markGrid',
autoScroll: true,
});
and get error:
1
TypeError: d[a] is not a constructor
...ng(this.enableUrlEncode)?this.enableUrlEncode:"data"]=Ext.encode(h);k.params=l}e...

You are missing a store. Every grid needs a store. (this.ds is undefined => ds is probably dataStore)
I don't know what version you are working with. (check that by typing Ext.versions.extjs.version in the console)
In case you are working with latest ExtJS version (4.x) it is preferred to use Ext.define and Ext.create instead of using the 'new' keyword :)
Here is a working fiddle
Ext.onReady(function () {
Ext.define('MyApp.model.Mark', {
extend: 'Ext.data.Model',
fields: [{
name: 'id',
type: 'int'
}, {
name: 'annotation',
type: 'string'
}, {
name: 'mark_date',
type: 'date'
}, {
name: 'status',
type: 'string'
}]
});
Ext.define('MyApp.store.Marks', {
extend: 'Ext.data.Store',
//best to require the model if you put it in separate files
requires: ['MyApp.model.Mark'],
model: 'MyApp.model.Mark',
storeId: 'markStore',
data: {
items: [{
id: 1,
annotation: "Test",
mark_date: "2013-04-24 9:28:00",
status: "Done"
}]
},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});
var grid = Ext.create('Ext.grid.Panel', {
itemId: 'markGrid',
store: Ext.create('MyApp.store.Marks'),
loadMask: true,
width: 400,
columns: [{
header: 'Аннотация',
dataIndex: 'annotation',
width: 230,
flex: 1
}, {
header: 'Дата',
dataIndex: 'mark_date',
width: 30,
flex: 1
}, {
header: 'Статус',
dataIndex: 'status',
width: 30,
flex: 1
}]
});
var window = Ext.create('Ext.window.Window', {
renderTo: Ext.getBody(),
items: [grid]
});
window.show();
});
UPDATE
You are using an example from Ext 4.x => Ext.data.ArrayStore
can't be created via Ext.create but use the new keyword in Ext versions < 4.x :)
http://jsfiddle.net/Vandeplas/BZUxa/
Ext.onReady(function () {
var markCm = new Ext.grid.ColumnModel({
columns: [{
header: 'Аннотация',
dataIndex: 'annotation',
width: 230,
}, {
header: 'Дата',
dataIndex: 'mark_date',
width: 30
}, {
header: 'Статус',
dataIndex: 'status',
width: 30
}],
defaults: {
flex: 1
}
});
var markGrid = new Ext.grid.GridPanel({
store: new Ext.data.ArrayStore({}),
cm: markCm,
selModel: new Ext.grid.RowSelectionModel(),
stripeRows: true,
//height: 400,
//loadMask: true,
id: 'markGrid',
autoScroll: true,
});
var markWin = new Ext.Window({
id: 'markWindow',
layout: 'fit',
title: 'Спискок маркеров',
autoScroll: false,
//width:600,
items: [markGrid],
listeners: {}
});
markWin.show();
});

extJs column layout issue

I have 3 extJs Windows. Each have some form control and then two tabs that display chart. Currently all windows appear at the same place and i have to drag them to make them stand in a row like this | | | . How can i create a 3 columns on screen and place each window in one of them. Please find the code of one of the window below. And yes i have seen this link
http://dev.sencha.com/deploy/ext-4.0.7-gpl/examples/layout/table.html but it doesnt help my cause. None of the content is displayed if i create 3 column layout like the what's mentioned in the link. Please assume that all of windows have the same code and suggest a way. One more thing, i have closable, and maximizable feature in all of the windows.Thanks.

The problem is, the Ext.Window while being descendand of Ext.Panel does not abide by the rules of the layout like normal Ext.Panels do, it floats by itself and is constrained only by the limits of the DOM element they're rendered to (body by default).
This means that you'll have to jump some loops to position and layout the windows manually. You can also try to create some descendand class from Ext.WindowGroup to help you manage your windows and keep them nice and tidy.
