multiple bigwigs in one track?

Hi,

I love the jupyter integration. Works very well! Is multiple file source overlay in one track possible? I am looking to overlay bigwig data.

kind regards

Thanks, and thanks for being an early adopter. I am not active in the python or jupyter communities so feedback is especially important.

The following should work for the object you send to load_track. In general you can use any options described here for tracks, although in this case the merged option is not yet documented: https://github.com/igvteam/igv.js/wiki/Tracks-2.0

{
            "type": "merged",
            "name": "Overlay",
            "height": 50,
            "tracks": [
                {
                    "url": "http://hgdownload.cse.ucsc.edu/goldenPath/hg19/encodeDCC/wgEncodeBroadHistone/wgEncodeBroadHistoneGm12878H3k27me3StdSigV2.bigWig",
                    "name": "GM12878 H3K27me3 ChipSeq Signal",
                    "color": "rgb(200,0,0)"
                },
                {
                    "url": "http://hgdownload.cse.ucsc.edu/goldenPath/hg19/encodeDCC/wgEncodeBroadHistone/wgEncodeBroadHistoneGm12878H3k36me3StdSig.bigWig",
                    "name": "GM12878 H3K36me3 ChipSeq Signal",
                    "color": "rgb(0,0,150)"
                },
                {
                    "url": "http://hgdownload.cse.ucsc.edu/goldenPath/hg19/encodeDCC/wgEncodeBroadHistone/wgEncodeBroadHistoneGm12878H3k4me3StdSig.bigWig",
                    "name": "GM12878 H3K4me3 ChipSeq Signal",
                    "color": "rgb(0,150,0)"
                }
            ]
        }
