# Diagrams
Diagrams can be drawn on the image to represent various input data and results. Typically diagrams are associated with nodes or elements; for example, reactions or bending moments. These diagrams are displayed only if the related node or element is drawn.
Some diagrams are not associated with nodes or elements; for example, grid point loads. These diagrams are displayed if their position lies within the extents of the currently drawn structure.
Diagrams are specified using the Graphics > Display > Settings > Diagram settings command. Diagram settings is also available on the Graphic display toolbar. Giving this command opens the Diagram settings dialog box.
Diagrams can be applied just to a selection of nodes or elements. If this is required then the items should be selected prior to giving the Diagram settings command. Refer to the Applying adornments to a selection section for details.
Ranges of interest, units, numeric format, axes and scaling can be specified. Refer to the Diagram settings dialog box documentation for a full list of available options.
Some of the more frequently used diagram options are accessible directly from the Diagrams toolbar. Selecting diagrams from the toolbar has the same affect as specifying the data type in the Diagram Settings dialog box and leaving all other settings as default.
Refer to the Displaying data and results section for a full list of available diagrams.
Diagrams of several data types can be displayed together in a Graphic view. This can be done either from the Diagram settings dialog box, by using the New diagram tab when a diagram is already being displayed, or by using the Display favourites toolbar commands.
Where the diagram is of data that is stored by case, the case displayed is as specified in the Cases field in the Lists toolbar. Diagrams are drawn for each case referred to in the field; diagrams for each case are superimposed. Diagram envelopes are displayed for enveloping cases.
Note that resetting the display switches off all diagrams.
The Graphics > Display > Hide > Hide diagrams command temporarily switches any diagrams off. Diagrams may then be un-hidden by giving the Hide diagrams command again. Adjusting any diagram settings or rescaling the data while the diagrams are hidden automatically un-hides the diagrams. Hide diagrams is also available on the right-click menu.
