1. Setting the horizontal scale
Scaling of the horizontal axis is executed in the
Timescale
section. To determine the endpoints of the horizontal axis,
select the indicated endpoints from the drop-down menus
for date and time selection.
Automatic scale:
The starting point of the horizontal scale corresponds to the
start time of the logger data file; the endpoint
correspondingly being the end time of the logger data file.
User-defined scale:
Starting point and endpoint of the horizontal scale can be
adjusted through the respective user settings.
Info
When user-defined scaling is selected and the input
starting point is earlier than the start time of the logger
data file, the starting point of the graph time scale is
used as the start time for the logger data file.
When user-defined scaling is selected and the input
starting point is later than the end time of the logger
data file, the endpoint of the graph time scale is used
as the end time for the logger data file.
2. Setting the vertical scale
Scaling of the vertical axis is executed in the
Vertical scale
section. First, select the measurement channel and then the
