Programmatically setting track features for QuantitativeTrack

[mondegreen]

I am trying to set up several JBrowse 2 instances each with several dozen tracks that are pre-configured for optimal viewing by researchers. There are several track configuration details that I cannot seem to set programmatically, such as the "height" of a track, or "Summary score mode", "histogram fill". While I can manually configure these after setting up the browser and saving the session, given the number of tracks I would like to do this programmatically so an optimal view is provided up front to users.

Can someone direct me to documentation about how I can do this or provide me with what options are available? I am coming from Jbrowse1 where all the data was stored locally and could be easily manipulated programmatically.

Hi there,
The Summary score, and histogram fill are governed by settings on the renderer, it's a little tricky to access those settings since they are sort of 'sub-configs' of the track, but it looks like this

{
  "type": "QuantitativeTrack",
  "trackId": "mytrack",
  "name": "mytrack",
  "assemblyNames": ["myasm"],
  "adapter": {
    "type": "BigWigAdapter",
    "bigWigLocation": { "uri": "file.bw"  }
  },
  "displays": [
    {
      "type": "LinearWiggleDisplay",
      "displayId": "mytrack-LinearWiggleDisplay",
      "renderers": {
        "XYPlotRenderer": {
          "type": "XYPlotRenderer",
          "filled": false,
          "summaryScoreMode": "max"
        }
      }
    }
  ]
}

The way I generated the above config was by taking a bigwig track, copying it with "Copy track" to a session track, then "Settings" on the session track, then going through the configuration to edit the particular rendering options that I wanted, and then going to "About track" dialog -> "Copy config" button

There is currently no setting for track height but this will be added by #3030
