Store with type memory not loading the data

[sandeepmnit35]

I am getting json response and am trying to put json in store but it is not loading it properly.

Ext.Ajax.request({   
                       url: url,                                               
      success: function(xhr) {                       
   response = Ext.JSON.decode(xhr.responseText.trim());                          //alert(xhr.responseText.trim());                                                  
  for(i=0;i< response.data.length; i++)                                                     {                              instancestore[i] = Ext.create('Ext.data.Store', {           
                       autoLoad: true,                     
             model: 'RA.model.DataModel',    
                             proxy: {               
                       type: 'memory',           
                           data: response,      
                                reader: {          
                                type: 'json',      
                                    root: 'data'      
                                }               
                   }         
                     });           
                                            }   

My Json output is :

{    "data": 
[{        "0": [{            "DowntimeEvents": 179,            "DowntimeHours": 78355        }]    },    {        "1": [{            "DowntimeEvents": 176,            "DowntimeHours": 97835        }]    },    {        "2": [{            "DowntimeEvents": 140,            "DowntimeHours": 100501        }]    }]}

I tried below code but it is passing null value of DowntimeEvents and DowntimeHours in the store.

 Ext.Ajax.request({    
                                    url: url,     
                                                success: function(xhr) {   
                       response = Ext.JSON.decode(xhr.responseText.trim());  
                        //alert(xhr.responseText.trim());               
                                     for(i=0;i< response.data.length; i++)                                                     {                            alert(response.data[0].DowntimeEvents);                        
               
          instancestore[i] = Ext.create('Ext.data.Store', {            
                      autoLoad: true,               
                   model: 'RA.model.DataModel',        
                          data: response.data[i],                 
                 proxy: {            
                          type: 'memory',           
                                                                reader: {     
                                     type: 'json',       
                                                                     
    }                               
   }                      
        });                               
                        }

First off you have some config that are in the wrong place or are not truly valid:

var store = Ext.create('Ext.data.Store', {
    model : 'RA.model.DataModel',
    data  : response,
    proxy : {
        type  : 'memory',
        reader : {
            rootProperty : 'data'
        }
    }
});

Your response is a little too nested, instead of this:

{
    "data" : [
        {
            "0" : [
                {
                    "DowntimeEvents" : 179,
                    "DowntimeHours"  : 78355
                }
            ]
        },
        {
            "1" : [
                {
                    "DowntimeEvents" : 176,
                    "DowntimeHours"  : 97835
                }
            ]
        },
        {
            "2" : [
                {
                    "DowntimeEvents" : 140,
                    "DowntimeHours"  : 100501
                }
            ]
        }
    ]
}

should really be:

{
"data" : [
{
"DowntimeEvents" : 179,
"DowntimeHours" : 78355
},
{
"DowntimeEvents" : 176,
"DowntimeHours" : 97835
},
{
"DowntimeEvents" : 140,
"DowntimeHours" : 100501
}
]
}

and you are good now.

I need to store data on index basis for different date thats why I am using instance[i] and sending indexes in json response so I can store the data on index basis.

My json is having data for 3 different date and I am using slider with play button to render the graph for 3 different date so I need to have data on index basis in store .

Can you please let me know how can I do this?
Thanks
