Dearl list,
can anyone point me to a function or library that can create a graph similar to
the one in the following powerpoint presentation?

(pages 36-37)
In order to try to explain the graph, the way I see it in R terms is something
like this:
the "p-q" axis is a vector of positions (for example, seq(0,5000000,1))
the "Chr1-Chrx" is a vector of units, in this case chromosomes (so something
like seq(1,10,1))
the plotted data is observations for each unit at each position
I guess the fancy gradient on the highest peaks is tougher to get (knowing I am
not an R expert), but just plain blue would suffice.
I have checked some of the graphs in the R graph gallery but I don´t think any
of them would work
Hi Dave,
This is a sort of 2.5D plot, with each chromosome being a 2D plot spaced
out on the z axis. If we assume that it is a static viewpoint, it would
be a case of drawing the parallelogram "base", then overlaying a
sequence of polygons with the appropriate offset to give the 3D
appearance. My eyeball says that there is no perspective correction.
Doable, but I would advise asking on the Bioconductor mailing list first.
Jim
