RE: st: Grid lines on top of shaded time series graph

[Nick Cox <n.j.cox@durham.ac.uk>]

Grid lines are automatic with e.g. 

-xla(, grid)-

Thank you both for your suggestions. I was afraid that I would have to
replace the grid lines with other line plots as in Maarten's example.
This solution works, but it is specific to each graph, and I have to
draw many of them. Maarten chose 5,10,15 and 20 as values for the
gridlines and knew the horizontal range of the lines. Any suggestions
on how to choose these values automatically depending on the graph?

Thanks,
