Time axis with valueFormatString not working

[ahmedcharef]

Hi I want to render a time axis chart,

var chart = new CanvasJS.Chart("rssi",{
		exportEnabled: true,
		zoomEnabled: true,
		title:{
			text:"RSSI signal / Date time"
	     },
	     axisX: {
        	intervalType: "hour",
        	valueFormatString: "YYYY-MM-DD HH:mm:ss",
        	labelMaxWidth: 100, // change label width accordingly
      	    },
	    axisY: {
	        title: "Downloads"
	    },
		data: [{
			type: "area",
			name:" RSSI value",
			showInLegend: true,
			xValueType: "dateTime",
			markerType: "square",
			color: "#F08080",
			dataPoints : dataPoint
		}]
	});
	chart.render();

Here is my datapoints:

0: Object { x: Date 2018-01-07T20:51:41.000Z, y: -67 }
1: Object { x: Date 2018-01-07T20:51:05.000Z, y: -6 }
2: Object { x: Date 2018-01-07T20:51:05.000Z, y: -21 }
3: Object { x: Date 2018-01-07T20:51:05.000Z, y: -29 }
4: Object { x: Date 2018-01-07T20:51:06.000Z, y: -44 }

@ahmedcharef,

Passing the Date to dataPoints in the standard JavaScript DateTime format new Date("2018-01-07T20:51:05.000Z") will work fine in your case. Please take a look at this jsfiddle.
