I'm trying to make a BEDGRAPH track to share with others on UCSC.

I have 4 contigs, followed by 4 more contigs (a total of 8). The only differences between the first 4 and the second 4 are the color and positions (they directly abut one another - as you can see from my code below):

I need to show these contigs on the same y-coordinates (Pos1's all need to be on the same y-coordinate, but next to each other on the x-coordinate)

But when I import this as a custom track, I get two sets of 4 sequences each, with the first left and above the second set). I need the second set right next to the first 4.

Thanks in advance for any ideas on this!
