Dear All, I would appreciate it if you would let me know how to change the scale of my data tracks when plotting on Gviz. My data ranges from 0-0.4 in values but I want to keep the scale as 0-1 for every data track to prevent skewing of representation. I tried playing with a few commands but was unable to achieve this. Here is my current data track: dTrack <- DataTrack(hct.mergegr, data = t(as.data.frame(elementMetadata(hct.mergegr))), genome = "hg19", chromosome = "chr17", name = "HCT116 Methylation", col = "red", from= 0, to = 1) the from and to does not alter the scale and my data track does not range the 0-1 that I would like it to. Is there some other command I can use here? Or does this range need to be specified while plotting and not while creating the data track? Thank you for the help, Kurinji Graduate Student Johns Hopkins University/University of Southern California [[alternative HTML version deleted]]

Hi Kurinji, Try adding ylim = c(0,1) to the DataTrack call. dTrack <- DataTrack(hct.mergegr, data = t(as.data.frame(elementMetadata(hct.mergegr))), genome = "hg19", chromosome = "chr17", name = "HCT116 Methylation", col = "red",ylim = c(0,1)) Steffen On Thu, Jun 7, 2012 at 11:06 AM, Kurinji Pandiyan < kurinji.pandiyan@gmail.com> wrote: > Dear All, > > I would appreciate it if you would let me know how to change the scale of > my data tracks when plotting on Gviz.
