Methylation Data: Igv?

Question

[Rm]

I have methylation data:

 chr coordinate methylation_score
    1     1203457 0.5
    2      1307889 0.9 
..
..

How do I plot them in IGV. I want it to display as bar or heatmap according to the methylation score. I converted above data to .bed file; I can visualize, but not according to the scale of methylation score.

Does the data need to be any other format?

Thanks for your inputs.

After going through IGV manual little deep; Icould able to plot it. SEG file format could support the methylation data to report it as heatmap or bar graphs. I plotted "methylation read coverage" as "num.mark" and methylation_score (C/C+T) as "seg.mean" Example: example.seg

ID      chrom   loc.start       loc.end num.mark        seg.mean
