title: How to fit a*e**bx function via gnuplot?
body: <p><strong>Upon running this code on my file, it fits nothing.</strong>  </p>
  
  <pre><code>f1(x) = a*e**(b*x)
  a = -1
  b = 10000
  fit f1(x) 'myFile.txt' via a,b
  plot 'myFile.txt' with points lc rgb"blue" title ' '
  </code></pre>
  
  <p>Does gnuplot understand 'e' or do we need to declare its value? <em>i.e. 2.7182.</em></p>
