Dynamic real-time data – xaxis scale

[dennisnguy]

Hi Everyone,

I using spline chart with dynamic real-time data. x-axis is time and displayed in minutes and seconds.
axisX: {
title: “Time”,
intervalType: “second”,
valueFormatString: “mm:ss”
},

How can I set x-axis to update data in the scale of 60 seconds.
For example, at start the chart will have the value from 0:0 to 0:59, a minute later the x-axis has value from 1:00 to 1:59, The chart updates the time linearly. from example 1:01-2:00, 1:02- 2:01, …., 2:00 – 2:59, …

Thanks in advance
