If there is no data for a pen, or if the data is outside the vertical axis range, the pen does
not appear in the chart.

Pen icons

Pen icons appear at the right edge of the chart at run time, if you choose to show them.
The icon’s position indicates the pen’s most recent recorded value (from the value table),
even if the trend is paused or if the most recent value has not been plotted yet.

Pen markers

Pen markers are symbols that indicate data points. If data is plotted frequently, the
markers might not appear as distinct, separate symbols. For example, see the lowest pen in
the illustration on page 28-5.

Chart types

Standard vs. XY Plots

You can create a standard chart, which plots tag values against time, or an XY Plot chart,
which plots one (or more) tag’s values against another’s.

This illustration shows what an XY Plot chart could look like:

Notice that the horizontal axis labels show the range for the specified x-axis pen. The time
period covered by the chart is at the upper left.
