Remove or suppress legends from dotplot class panels #688
Description
Right now the dotplot class has an option that accepts only 2 options ( "Bottom","Right") for LegendPosition. We have a case in one of our apps that the resulting ReducedDimPlot has over 50 discrete labels; this makes the legend take up too much of the space. We would like to be able to use LegendPosition = none which ggplot will simply not create the legend.
