The variable that the Isovolume operator uses does not necessarily have to match the plotted variable. If the plotted variable is to be used, the Variable text field must contain the word: default. If you want to make the Isovolume operator use a different variable so you can, for example, plot temperature but only look at regions that have a density greater than 2g/mL, you can set the Isovolume's variable to temperature. To make the Isovolume operator use a different variable, select a new variable from the Variable variable button in the Isovolume operator attributes window.
If you apply this operator to a plot that does not operator on scalar variables such as the Mesh or Subset plots, be sure to set the variable because the default variables for those plots is never a scalar variable. Without a scalar variable, the Isovolume operator will not work.
