title: How to make an equilateral triangle using GNUplot?
body: <p>I'm trying to plot my data into two-dimensional barycentric equilateral triangle using GNUplot. </p>
  
  <p>I'm using the following commands:</p>
  
  <pre><code>unset border
  unset xtics
  unset ytics
  set arrow 1 from 0,0 to .5,sqrt(3)/2 nohead front lt -1 lw 1
  set arrow 2 from 0,0 to 1,0          nohead front lt -1 lw 1
  set arrow 3 from 1,0 to .5,sqrt(3)/2 nohead front lt -1 lw 1
  set label 1 "1" at 0.5,sqrt(3)/2+.05
  set label 2 "2" at 1+.05,0
  set label 3 "3" at -.05,0
  plot 'data.file'
  </code></pre>
  
  <p>The above mentioned commands does not create an equilateral triangle instead its making Isosceles triangle.</p>
  
  <p>Please help me!</p>
  
  <p>With Regards,
  Swati </p>
