title: gnuplot - Does `set xrange [x_min:x_max]` limit the ranged used for function fit?
body: <p>Simple question - the range drawn on a plot can be changed with the <code>set xrange [x_min:x_max]</code> command.</p>
  
  <p>Does this command also limit the range used when fitting a function using the data fitting tools in gnuplot? Is there a way to manually specify the ranged used for function fits? (One guess might be the command <code>every</code>? Do I need to over-ride <code>xrange</code> using <code>every</code>?)</p>
  
  <p>The reason I ask is that I am using xrange to plot outputs zoomed in on the low value x region to view transient behaviour more clearly, but I think this may be "slicing off" values from the function fitting at larger x values outside the xrange region selected?</p>
