title: How can you watch gnuplot realtime data plots as a live graph, with automatic updates?
body: <p>I plot a lot of graphs in gnuplot.  These graphs are based onn sensor readings from around the solar power system.</p>
  
  <p>Each graph has needed to be updated by typing something like </p>
  
  <pre><code>load "solar
  </code></pre>
  
  <p>where solar is a gnuplot program that performs the plot showing the condition of the 24 V (500Ah) battery bank and leaves it on the screen so I can do a regional screen capture for storage.</p>
  
  <p>In this particular case, the numbers come in at 2-minute intervals.  Unless the inverter is turned on, in which case they come in at 20 second intervals.  So I end up typing that command a lot just to see how clean the signal is.</p>
  
  <p>So the question came up as to whether I need to continue to tell it to load the program every time I want to see updates.  </p>
  
  <p>How can I actually make it automatically live?</p>
