The information on the XYCursor point pair is shown in a box on each
axis. If the tags are digital or string, the text value is shown in the box
rather than a numeric value. Placing the mouse cursor over one of the
cursor boxes shows the time of the event.
Bad Status Indicators
If a single point of a pair contains a bad status, an X appears on the axis of
the good point at its value. If both points of a pair contain bad statuses, an
X appears at the origin of the plot.
The XYPlot symbol supports Questionable, Annotated, and Substituted
indicators.
Out of Range Indicators
When a point on the XYPlot falls above or below the X or Y scale range, it
is not visible. This may be because the plot is zoomed or because the scales
have been set within a certain range that does not cover the actual data.
In order to indicate there is a point outside of the visible area, an X is used.
By default, a straight line connects the points in the order that they are
plotted. This line attempts to connect hidden points as well. An X is placed
at each position where this line crosses the top or bottom of the plot area.
Too Many Points
When an X Tag has too many points to show on the plot, you receive and
error message and no points are shown. The maximum number is 10,000
points.
Examples of XYPlots
For these examples, the X-axis represents one of the values in the pair and
the Y-axis represents the other. The configuration of these axes regarding
minimum and maximum values and interval (or unit) settings is left to you.
