          Description

          The inverse log functions for graph tracks don't make sense.

          Is it taking the inverse of the log ? If so, its doing it wrong.
          Is it taking the log of the inverse? nope.
          What does inverse log mean?
          The user guide has no info on this.

          We an take the inverse (which does seem to working) of the log (which does seem to be working) and we get the values we expect. And these values are very different from the values generated by inverse log.

          See the instructions on the track operations release testing page.

                For clarification, the inverse log is equivalent to an antilog.
