title: Combining solid and dashed format on same line in google line chart
body: <p>I am using google line chart for my application to display current and projected values. The data I receive would be from database (both current value and projected value). I would like to see solid line till the current score and dashed line for projected score in future. Please let me know how to achieve the this.</p>
  
  <p>Example:</p>
  
  <p>Match : my current expense on 10th may is $5000 and by 7th october it will be $10000 then till $5000, I will have solid line curve and afterword till $10000, I would like to have dashed line. </p>
  
  <h2>Note: This is similar to zones feature in high charts. But I would like to know if the same can be done in google chart.</h2>
