ColorWritesMixin

Auto-generated from the @jbrowse/mobx-state-tree model in the source — see the developer guide for concepts. Built into JBrowse core. View source.

The writes a display's color object takes from a menu row or a picker: the field it paints by (colorByField) and the constant every feature paints (setColorValue). Each rewrites the object as written, so what a pick leaves alone stays as it was, and a pick of what already paints writes nothing, since every color tier keys on the object's arrays. A dialog's Apply button writes the whole object through applyPlot, which rebuilds the display's config for the draft, too dear for a picker writing once per drag frame
