5.5.2.9   Change Sample Type to MAX, MIN, AVG or LAST

To change a Tag from LAST to MAX, you have to pick the tag from the left menu, then use the UP/down arrows at the bottom right to change to AVG or MAX or Min or LAST.  This does one tag at a time so you can compare MAX of one tag to MIN of another. Also, AVG, MAX, MIN only applies for time frames of 1 minute or 1 hour.
