# BedGraphAdapter

Auto-generated config schema for the current JBrowse release — see the
[config guide](https://jbrowse.org/jb2-staging/docs/config_guide) for concepts. Provided by the `bed` plugin.
[View source](https://github.com/GMOD/jbrowse-components/blob/main/plugins/bed/src/BedGraphAdapter/configSchema.ts).

## Example usage

```js
{
  type: 'QuantitativeTrack',
  trackId: 'my_track',
  name: 'My track',
  assemblyNames: ['hg38'],
  adapter: {
    type: 'BedGraphAdapter',
    uri: 'https://example.com/signal.bedGraph',
  },
}
```

_See the **Config slots** section below for all available configuration fields._

used to load plain-text bedGraph signal files. Loads the whole file into memory,
so prefer the BedGraphTabixAdapter for large files.

## Config slots

These slots go inside the track's `adapter`:
`"adapter": { "type": "BedGraphAdapter", ... }`. It also accepts the
[shorthand](https://jbrowse.org/jb2-staging/docs/config_guides/file_types#the-uri-shorthand) keys `uri`,
`baseUri` in place of writing a location slot out. Slot types (`fileLocation`,
`frozen`, ...) are explained in the
[config slot types reference](https://jbrowse.org/jb2-staging/docs/config_guides/slot_types). Slots a base
configuration contributes are listed here too, so this table is the whole
surface.
