Showing the value of pens at various positions
The value bar shows the value of each pen in the trend, at the position you select on the
trend chart.
The color of the value bar changes automatically, so it is visible for all background colors.
For example, if the trend background color is black, the value bar color will be white. If
the trend background color is white, the value bar will be black.
A tilde ( ~ ) indicates an approximate value. An approximate value is shown when there is
no value for the pen at the exact time stamp of the value bar. The approximate value is
based on the nearest available reading.

 Click the trend where you want the value bar to appear.
To hide the value bar
 Click the trend’s vertical axis.
You can also right-click the trend, and then select Show value bar. A check mark
indicates the value bar is visible. No check mark indicates the value bar is hidden.
