title: How to calculate area under the curve from logarithmic plot with xmgrace?
body: <p>I have plotted my data on linear scale in <code>xmgrace</code> by using these numbers:</p>
  
  <pre><code>0.001       0
  0.00589391  0.10
  0.155206    0.20

  0.43222     0.40
  0.436149    0.50
  0.489194    0.60
  0.611002    0.70

  0.939096    0.90

  <p>I have use <code>xmgrace</code> in Ubuntu to plot my date and calculate area under the curve (AUC; Data ->Transformation -> Integration-> SumOnly).
  After converting linear curve to the logarithmic one, I am having a problem with calculating area under logarithmic curve.
  Has anybody else encountered similar issue?</p>
