Stepped Area Chart showing Slanting lines in steps

[Himanshu Tongya]

We are using a stepped area chart to draw the steps for ON and OFF state.

We are using below code -

google.charts.load('current', {'packages':['corechart']});

     google.charts.setOnLoadCallback(drawChart);

      function drawChart() {

        var data = google.visualization.arrayToDataTable([

          ["Time",  "State"],

          [new Date(Number("1553076311009")), 0],

          [new Date(Number("1553076312010")), 1],

          [new Date(Number("1553076313011")), 0],

          [new Date(Number("1553076314012")), 1],

          [new Date(Number("1553076321013")), 1],

          [new Date(Number("1553076331014")), 1],

          [new Date(Number("1553076341015")), 0],

          [new Date(Number("1553076351016")), 0],

          [new Date(Number("1553076361017")), 1],

          [new Date(Number("1553076371018")), 0],

          [new Date(Number("1553076381019")), 1],

          [new Date(Number("1553076391020")), 1],

          [new Date(Number("1553076392021")), 1],

          [new Date(Number("1553076393022")), 0],

          [new Date(Number("1553076394023")), 0],

          [new Date(Number("1553076395024")), 1],

          [new Date(Number("1553076396025")), 0],

          [new Date(Number("1553076397026")), 1],

          [new Date(Number("1553076398027")), 1],

          [new Date(Number("1553076399057")), 1]

        ]);

        var options = {

          title: 'Machine state chart',

          vAxis: {

          title: 'State',

          ticks: [{v:1.00, f:'ON'}, {v:0.00, f:'OFF'}]},

          hAxis: {

          title: 'Time'},

          isStacked: true

        };

        var chart = new google.visualization.SteppedAreaChart(document.getElementById('chart_div'));

        chart.draw(data, options);

      }

That code is with sample data, we have around 500 entries so charts should be like Desired.png but it is looking like Reported.png.

Any suggestion to resolve this issue?

Thanks
