Hello,
I am using ggbio to plot a series of genomic tracks with a shared genomic x-axis. As described in the ggbio documentation, I am using the tracks() function to align them. I had expected that when I added an Ideogram using the Ideogram() function, that it would be aligned with this genomic axis. However this does not appear to be the case. So my question is, how can I add an ideogram to tracks so that it is aligned with other plots.
To make this clear I am trying to draw three plots looking like this:
IDEOGRAM
Data Track 1
Data Track 2
Both data tracks have the same x-axis (some chromosome) and are aligned well by the tracks() function. The ideogram draws, but is clearly not aligned in the same way. I know this as the ideogram is a different length to the data tracks, the centromeres do not line up. I am using hg19 if that matters.
Alternatively, is there another way to draw an ideogram and align a common x-axis across multiple plots using ggplot2?
Cheers,
Matt
