When a collection of objects are grouped, changes in the display range of one grouped object is applied to all objects (graph, thermometer, and or gauge) within that group.
There are three kinds of objects that display a Y-Axis, Graphs, Gauges, and Thermometers. Y-Axis grouping can be applied to any collection of these objects. When Y-Axis grouping is in effect, a change in Y-Min or Y-Max of one member appears in all members of the group. Y-Axis grouping of graphs only works if the graphs are displaying a common column. This feature is particularly useful when output of Temperature sensor is shown both in a Graph and a Thermometer since it allows the scaling of these two objects to be synchronized.
The Ungroup menu item simply releases the selected objects from their respective groups. If nothing is selected then all grouped objects are ungrouped.
Note: Inserting a thermometer will automatically group it to the existing graph.
