1. Open a trend in Run mode.

2. Hover your mouse pointer over the trend's legend. The mouse pointer changes to a hand

cursor

, and the trace in the trend is highlighted.

3. Click the legend item to hide or show the trace on the plot. If the trace has a regression

line configured, the regression line is also hidden. When a trace is hidden:

1. The trace name is dimmed in the legend and the description, value, and engineering units

are hidden (if they were shown before).

2. The space reserved on the legend for the description, value, and

engineering units collapses so that the trace under the hidden trace
is moved. This clearly shows the visible traces on the legend,
especially on a trend with many traces.

3. On a multi-scale trend, the scale associated with the hidden trace

is hidden.

4. On a single scale trend, the minimum and maximum values shown

on the scale may be adjusted.

You can show hidden traces by clicking their names a second time in the
legend, or by clicking the Revert button. All hidden traces are shown in
Build mode.

You can also right click a trend and select Show All or Hide All to make

traces visible or invisible.

Markers

Markers indicate data points and allow you to differentiate between traces
on a trend. There are three types of markers:

Actual data

markers

Actual data markers plot each value stored in the database. The color

of the trace and of the marker is the same. You can select the shape
of the marker, such as diamonds, circles, squares, or triangles, which

can be helpful for color- blind users and for monochrome monitors.
