Hello,
I have used layout() to produce to 2 plots on a page, leaving a plotting space above them. I would
like "Legend", which will actually be a real legend, to be centered above the two graphs.
Right now I am only able to position "Legend" above the second graph that I create...
obviously I am stuck in its margin space.
Is there a way to draw the legend in the empty plotting space above? Or is
there a way to center the legend in the margin space above the two graphs.
I am open to using par(mfrow=c(2,2)) rather than layout(), but it currently
produces the same result.
Hi John,
Try using par(xpd=NA) that allows you to draw anywhere on the device,
and then place your legend relative to the current plotting area. See
the help page for zoomInPlot (plotrix) for an example.
