  <p><strong>Reason :</strong> </p>
  
  <p>To show above data in chart I have used webservice that return string.</p>
  
  <p>Now for jsChart data needs without string double quote at 1st and last position.</p>
  
  <p><strong>What I had Tried :</strong> </p>
  
  <pre><code>data=data.replace(/^"(.+(?="$))"$/, '$1');
  </code></pre>
  
  <p>or</p>
  
  <pre><code>data=data.substring(1,data.length-1);
  </code></pre>
  
  <p>all above return with double quote.</p>
