rangeSet does not support sex chromosomes

[Max Levine]

I am trying to add coloring and annotation to CNVs using rangeSet but the coloring does not appear on sex chromosomes.

Hi there, and thanks for using Ideogram! Could you provide data and configuration for a minimal reproducible example?

[Max Levine]

Thanks for the speedy response! It is a great library.

Here is an example. Loss of 22q and Yp, should be dark blue, but only 22 is rendered.

  var config = {
    organism: 'human',
    assembly: "GRCh37",
    chrHeight: 300,
    chrMargin: 2,
    annotationHeight: 0.1,
    annotations: [{"chr":"22","start":14500000,"stop":51304566,"color":"rgba(0, 0, 0, 0)","name":"0+0"},{"chr":"Y","start":1,"stop":11604552,"color":"rgba(0, 0, 0, 0)","name":"0+0"}],
    rangeSet: [{"chr":"22","start":14500000,"stop":51304566,"color":"#000F4A","name":"0+0"},{"chr":"Y","start":1,"stop":11604552,"color":"#000F4A","name":"0+0"}],
    annotationsLayout: 'overlay',
    orientation: 'horizontal',
    rotatable: false,
  };

  var ideogram = new Ideogram(config);

I am also having trouble with annotations on GRCh37. When I press F12 (dev tools) in Edge, there is an error in the console which remains even when I remove annotations on the sex chromosomes:

I've resolved my issue - the annotation I was using had one annot starting with 0, not 1.
