markedLineWidth option doesn't seem to work

[makotech222]

I have a parcoords component set up and I'm trying to get the 'marked' data to appear very similar to selection via brushing. I've found that the line width option for marked doesn't actually change anything.

I'd appreciate also an easier way to make marked lines appear same as brushed lines. I'm using mark() to select data points that are selected in other components, and passed into parcoords. Brushed lines are used to propagate selected data back to other components.
