The horizontal scale start point and the end point can be
changed by the user.

If the custom scale is selected and the input start
point is lower than the start time of the logger
data file, the start point of the graph time scale
will still be the start time of the logger data file.
If the custom scale is selected and the input
end point is over the end time of the logger
data file, the end point of the graph time scale
will still be the end time of the logger data file.
Vertical Scale:
Select the measuring channel and unit. Then set the
channel’s minimum and maximum value.
Auto scale:
Selecting this item will allow the vertical scale to change
