Interpreting an XYPlot
In FactoryTalk Historian ProcessBook the XYPlot is a dynamic symbol. It
has specialized characteristics, such as its statistical calculations, which are
described in the following paragraphs.
Point Properties
Data may be retrieved from FactoryTalk Historian or from independent
data sets. Use the Tag Properties button or the right mouse menu Properties
item to determine the attributes of the points in your XYPlot.
Scroll Feature
Scrolling is available from the ProcessBook toolbar. When time scrolling is
used on an XYPlot symbol, all tags’ time ranges are changed to support the
scroll duration.
Plot Values
In a typical XYPlot, the current name for the X tag appears below the plot.
The current names for the different Y tags appear at the upper right. Below
each one is the correlation coefficient for that XY pair. The dots and lines
on the plot are colored to match the tag names.
Plotted pair values appear in a ToolTip over the plot when the mouse
cursor is hovering over an actual plotted point pair. The following
illustration shows an example.
