Hi Raymond, You might be able to get the plots you want with the 'cytoband' material provided in the Bioconductor package "SNPchip".
Check out the SNPchip data set 'cytoband' and the plot function "plotCytoband" for ideas. This material is used e.g. in Bioconductor package "VanillaICE" to add a chromosome graphic to the bottom of data plots of genomic data. You can see examples in the vignette PDFs.
