Hi

I would like to have a plot layout, on which line graphs are on the plot
area of an underlying bar graph.
How can I achieve this? I know about layout() and par() to create a
layout, but as far as I know, they assign non-overlapping plot areas.

Effectively, it should look as below:

|------------------------|
|                        |
|      |---|  |---|      |
|      |   |  |   |      |
|      |   |  |   |      |
|      |-L-|  |-L-|      |
|                        |
|                        |
|                        |
|                        |
|                        |
|                        |
|-the bargraph-----------|

L: the line graphs

Any help appreciated,

Rainer
