Thank you very much :) Now, its perfect. CanvasJS really has a great documentation and support. This topic can be closed.

I have solved 2 and 3.
.toFixed converts the number to sting. so, the chart rendering fails.
Also, the correct way to display a live data is to use shift method on the datapoint array. This is mentioned in the Docs

But I am still struggling with the 1st issue. The first point has the correct time axis. Then, for 10 seconds some ms is getting displayed and then again correct date-time is being displayed.

I am using the following hack to overcome this behavior. If the datapoint array length is 0, I am adding 2 more data points. 1. (x: 10 sec ago and y: 0) This does not look good because of the line continuity. Thus I am also adding 2. (x: 10 ms ago and y: 0)

if(dataPoints1.length==0){
		dataPoints1.push({
		x: new Date(Date.now() - 10000),
		y: 0
		});
	dataPoints2.push({
		x: new Date(Date.now() - 10000),
		y: 0
		});
		dataPoints1.push({
		x: new Date(Date.now() - 100),
		y: 0
		});
	dataPoints2.push({
		x: new Date(Date.now() - 100),
		y: 0
		});
	}
