Time scroll bar

The time scroll bar allows you to select the time for which the graphs of variables are
presented in the chart.
Description of time scroll bar
The time scroll bar is located above the plot area. The location of the scroll bar indicates
the location of the chart. Past time is to its left and future time to its right.
When the chart window is opened, the chart area on the left side of the scroll bar repres-
ents the available past time area, while the chart area on the right side represents the
available future time area. The time areas correspond to the maximums of the past and
future times of all the variable items in the chart based on the source tables defined for
the variables.
To view the graphs at different times, move the scroll bar. The time span remains
unchanged. Moving the scroll bar locks the end time, and the graphs are no longer
refreshed. To return to the original chart view, unlock the end time in the time bar.

during which we move from daylight saving time to standard
time, the indicator box is not disabled, allowing you to specify

time.
