Shared-variable graphs
are created the same way as other graphs in the designer, but have
the following additional requirements:
-
The entire graph must be created
from one data set. You assign the data set when you create the shared-variable
graph.
-
You also define the shared variables
when you first create the graph, before you add any plots. (You can
later add shared variables and remove unused shared variables.)
-
All plots are created using only
the shared variables that have been defined for the graph.
