It is an analysis presenting a table and/or a graph, achieved from one (at minimum) or several variables. For example, for a cross analysis, the object contains two variables (one in line , one in column) and includes an associated table. If we decide to display the graph corresponding to the table, this one will be added to the object. So, it will be the same object but containing more elements. The modifications of the content of an object are defined via the properties of the object.
