Committing before trying to stabilize the legends.
Finally stabilized the station legend so that the same color and symbol represents one station across all analytes in the basin.  This involved changing the NDs/NAs to -999, then changing the y coordinates to only show positive numbers.  The "any" function helped filter out basin/analyte combinations that did not have any detections.
Plus some other minor changes.
