Dynamic json chart

[techillin]

I'm trying to use Sencha Touch Charts with a JSONStore to dynamically display a chart from information provided by JSON, series and data. This was possible with ExtJS 3 with the metaData property.


How can I accomplish the same with Sencha Touch Charts?

Load the store outside the chart and when the store loads, create the chart.

I'm sorry but I can't get it to work. A simple example would be nice.

I wan't someting like this to produce a chart, none of the fields (except timestamp) can be hardcoded because it needs to be fullt dynamic.

{    "metaData": {
        "root": "series",
        "fields": [{
            "name": "timestamp"
        }, {
            "name": "Unit 1",
            "mapping": 2345
        }, {
            "name": "Unit 2",
            "mapping": 5647
        }, {
            "name": "Unit 3",
            "mapping": 1436
        }]
    },
    "series": [{
        "timestamp": "Jan",
        "1436": 10,
        "5647": 6,
        "2345": 4
    }, {
        "timestamp": "Feb",
        "2345": 10,
        "1436": 9,
        "5647": 7
    }, {
        "timestamp": "Mar",
        "2345": 10,
        "5647": 7,
        "1436": 4
    }]
}

What if i want the labels also to be dynamic not hard coded?

How do i refresh and reload the data. Say i reload the store with new data. How do i rerender the chart.

The chart should hear when the store loads. The examples have a refresh button that simulates this.

@simon i am afraid then when a store calls a loadData the chart is refreshed but it does not update the series in the charts and so if we have added a new data or field in the store then the chart does not reflect this change is only redraws or refreshes the chart with same old store data..

i tries this with sencha 4.0.1 charts and also on touch chars
