How to (1) change default color in AxisBox and (2) add reference line in only one Y-axis variable in grouped Y plots?
In the chart generated by the script below I would like to change the color of the lines indicated by the red arrows ("the separator lines") to purple. Also I would like to add a horizontal reference line only for the lowest y-axis variable (in this case PNP1).How to do these via JSL?(Note in my actual case the y-axis data is not from a column unlike in this example case)Names Default To Here( 1 )
