title: JMeter - saving results + configuring "graph results" time span
body: <p>I am using JMeter and have 2 questions (I have read the FAQ + Wiki etc):</p>
  
  <ol>
  <li><p>I use the <a href="http://jakarta.apache.org/jmeter/usermanual/component_reference.html#Graph_Results" rel="noreferrer">Graph Results listener</a>. It seems to have a fixed span, e.g. 2 hours (just guessing - this is not indicated anywhere AFAIK), after which it wraps around and starts drawing on same canvas from the left again. Hence after a long weekend run it only shows the results of last 2 hours. Can I configure that span or other properties (beyond the check boxes I see on the Graph Results listener itself)?</p></li>
  <li><p>Can I save the results of a run and later open them? I know I can save the test plan or parts of it. I am unclear if I can save separately just the test results data, and later open them and perform comparisons etc. And furthermore can I open them with different listeners even if they weren't part of original test (i.e. I think of the test as accumulating data, and later on I want to view and interpret the data using different "viewers").</p></li>
  </ol>
  
  <p>Thanks,</p>
