AJAX functions

The RGraph svg libraries incorporate ajax functions that make it easy for you to fetch data from your server and then use it to create your charts. You can use them by simply including the file RGraph.svg.common.ajax.js in your page and then use the functions like the following example code shows.

There's also a dedicated csv reader that fetches data via ajax. The csv reader is documented here.

    RGraph.SVG.AJAX.getJSON('/getdata.html?json', function (json)
        var bar = new RGraph.SVG.Bar({
            id: 'chart-container',
            data: json.data,
            options: {
                xaxisLabels: json.labels,
                marginInner: 5,
                backgroundGridVlines: false,
                backgroundGridBorder: false,
                yaxis: false,
                yaxisScaleMax: 100,
                marginLeft: 50,
                shadow: true,
                shadowOpacity: 0.1,
                colors: ['Gradient(orange:orange:white)']

The available functions can just fetch the desired resource or can go further, such as the getJSON function which doesn't return the string that the server provides; it returns a usable javascript object for you. Here are the functions:
