@umustaphax,
While creating a dynamic chart, to redraw a chart, you will just have to change/add the dataPoints to the dataPoints array and then call chart.render() again.
Please take a look at the code snippet below,
var xVal = dps.length + 1; var yVal = 100; var updateInterval = 1000; var updateChart = function () { yVal = yVal + Math.round(5 + Math.random() *(-5-5)); dps.push({x: xVal,y: yVal,}); xVal++; chart.render(); }; setInterval(function(){updateChart()}, updateInterval);
Please refer to this documentation page for a step-by-step tutorial on how to create a dynamic chart.
