When several graphs are grouped together, a change in the scale of one graph is applied to all graphs within the group. For example, when x-axis grouping is in effect, a change in either XMin or XMax of one graph sets that value for all graphs of the group. When the x-axes of graphs are grouped, the Analyze-Examine indicator line will be displayed on all graphs in the group when the Analyze or Examine features are active.
To create an x-axis group you must first select the objects which are to be in the group. Then, choose Group Graphs (X-Axes) from the Page menu. Note: You must have more than one groupable object selected to enable the menu item.
Choosing Ungroup from the Page menu simply releases the selected objects from their respective groups. If nothing is selected then all grouped objects are ungrouped.
