title: sorting data on x-axis in google line chart
body: <p>I'm using google line chart to plot data by timestamp(x-axis).</p>
  
  <p>my problem is that the x-axis is not being sorted automatically by the google charting.</p>
  
  <p>e.g. "15:45:23 678" data point which should be the first in the chart is being shown at #2. If I put it at the first place then it is fine. That means Google chart doesn't care about the data and it plots as it sees them.</p>
  
  <p>The issue is that my data set is huge and sorting it based on x-axis data takes lot of time. is there any flag in the line chart which could sort it in the browser?</p>
  
  <p>below is the sample data:</p>
  
  <pre><code>['x', 'c1', 'c2', 'c3', 'c4', 'c5', 'c6'],
  
  ['15:48:13 744', 0, 0, 0, 0, 0, 0], 
  
  ['15:45:23 678', 5, 17, 36, 3957, 20, 21], 
  
  ['15:48:18 749', 0, 0, 0, 0, 0, 0]
  </code></pre>
