Ajax Google Visualization API Gauge with jquery

Question

I am looking to create a dashboard gauge that updates via ajax. Below is the code I have. I have the ajax code but just am unsure on how to update the gauge. Any suggestions?

You can use the same kind of code for update too. You need to create a new data table instance and call the draw function of the chart again (very similar to how you updated the first time).

        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Label');
        data.addColumn('number', 'Value');
        data.addRows(1);
        data.setValue(0, 0, 'Tempature');
        data.setValue(0, 1, 76);

        chart.draw(data, options);
