The Plot Container stores all Plot profiles with common definitions to create several results graphic plots. As shown in the image below, the upper list has all Plot Containers with plot definitions of the same type while the bottom list has the plot files of the selected container.
As shown in the image below, while the Plot Container list is editable with the extra menu buttons "floating" on the top right, the Plot file list is modified with the common menu, at the top right, just below the Recalculate button. Predefined standard plots can be directly created with the option Macro.
The information button gives access to edit the selected Plot file, where, as shown in the screenshot below, in the RM Plot editor menus each View, Filter, and Object can be selected for inserting modifications. The Variable button allows for editing the Variables option.
More technical information can be found at the Help/F1 button and at the RM Bridge User Guide document, in section 8.4 Graphical Results Presentation.
