    With the code below, the browser tab hangs, circling indefinitely.
    The issue appears to be the rendering of two data-points that are very close apart

    series1:
    dataPoints: [
    { x: 3.001084, y: 235 },
    ]

    series2:

    dataPoints: [
    { x: 2.991214, y: 234 },
    ]

    If I move the data points x of the series by 1 (increase or decrease), it works fine.. Looks like a bug?

    try changing the 2.991214 to 2.591214 and the chart would load without an issue.

    I am facing similar issue. Any update on the fix? In my case the multiple series are sharing same data. And I cannot control data and prefer not to manipulate it.

    @ravidasari,

    Sorry for the inconvenience caused. There seems to be issue with axis-range when there are less number of datapoints (1 datapoint in 2 dataseries in this case). As we were busy working on some other important features, we were unable to fix this. We will prioritize and fix it in future versions. Meantime you can get it worked by setting minimum & maximum manually. Please find the code-snippet below.

    Please take a look at this JSFiddle for complete code.
