Check the Show Vertical Bar checkbox to display a vertical bar across all points on an
X axis. At the bottom of the trend chart, timestamps will be adjusted when you click
inside the trend chart and drag the vertical bar across the chart.
When Daylight Savings Time (DST) occurs, the timestamps displayed will
automatically update to reflect the time change. If you adjust the start time to an
earlier start time, the timestamps reflected will coincide with DST even if the DST
transfer did not occur until later.
You must disable Auto Refresh (by clicking the red square) before you enable the
Show Vertical Bar feature.
