- Graph type :
If no graph type-> No button "Graph"
If a single type of graph -> "Graph" button with graph type imposed
If several types of graph-> "Graph" button with choice of type of graph required amongst those parameterised.

- Number of lines/columns
For dimensioning the variables necessary to print the graph.

- Enter a column number Y/N.

If a type of graph is chosen, or the number of lines and/or columns is nil, or the number of a column is to be entered, pressing the button "Graph" causes the entry in the parameter window.

The "Graph" button is inactive when the main window grid does not contain a line.
