Rotating a graph in Layout

Dear All,
I am looking for an option to rotate a graph included in the layout by 90 degree. This is possible if I plot the data x(y), but for analysis purpose I would like to keep it in y(x).

There is no provision for rotating a graph, or any object, in a page layout.

You can rotate the graph itself using the Swap X & Y Axes feature in the Modify Graph dialog.
You can rotate the layout. I mean set up the layout as landscape rather than portrait.
