    I hope I have understood this correctly. The code in comments is the remainder of the data (from 12pm to 4pm). Without this data the graph will show a partial graph as you require.

    <html>
  <head>
    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = new google.visualization.DataTable();
        data.addColumn('string');
        data.addColumn('number');
        data.addRows(8);    
        data.setValue(0, 0, '9AM');
        data.setValue(2, 0, '11AM');
        data.setValue(4, 0, '1PM');
        data.setValue(6, 0, '3PM');
        data.setValue(7, 0, '4PM');

        data.setValue(0, 1, 5480); // 9AM
        data.setValue(1, 1, 5475); // 10AM
        data.setValue(2, 1, 5490); // 11AM
        data.setValue(3, 1, 5490); // 12PM
        /*
        data.setValue(4, 1, 5500); // 1PM
        data.setValue(5, 1, 5490); // 2PM
        data.setValue(6, 1, 5530); // 3PM
        data.setValue(7, 1, 5560); // 4PM
        */

        var chart = 
           new google.visualization.AreaChart(document.getElementById('chart_div'));
           chart.draw(data, {width: 500, height: 240,
                          vAxis: {minValue: 5460, maxValue: 5560},
                          colors: ['#76A4FB'],
                          legend: 'none'
                         });
           }
    </script>
  </head>
  <body>
    <div id="chart_div"></div>
  </body>
</html>

    I hope this helps.
