动态json图表

Question

我正在尝试使用带有JSONStore的Sencha Touch Charts，根据JSON，系列和数据提供的信息动态显示图表。使用带有metaData属性的ExtJS 3可以实现这一点。

如何使用Sencha Touch Charts完成相同的操作？

Answer 1

//    Am using ruby for the webservice calls.

// First u have to create model and store for that



// model 
 Ext.regModel('samplemodel', {
idProperty: 'name',
fields: [ { name: 'name', type: 'string' },
              { name: 'data', type: 'int' }
            ]
});

// store
Ext.regStore('SampleStore', {
model: 'samplemodel',
storeId: "sampleStoreID",
sorters: [ {
    property: 'name'
}]
});

// and create a variable for the store 

var sampleStore = Ext.getStore("SampleStore");

// call the webservice and store it in array,
// bind the response to the store,
// use the store variable in the chart.
