The Average command determines the average value for all or a selected portion of the data plotted on the y-axis. If you selected a region of the curve using the Select X Region tool, then the command calculates the average of the values within the selected region only. The command operates on all visible traces, and the results are placed on a new Average page, assuming one does not already exist. If this page already exists, the new information overwrites the old information.


  1. If the calculation is to be based on only part of the curve, select the appropriate portion using the Select X Region tool.
  2. Once the desired portion of the curve is selected, select Average from the document window. As soon as you select this command, the computer begins to calculate the average y-values for each visible trace.
  3. Results are presented both on their own page, and in the QuickView area at the bottom of the chart. You can hide the QuickView window by clicking the X on the side-bar of the QuickView.
