Sticks to next mode for two colums of a 2-dimensional wave

I would like to plot to colums of a 2-dimensional wave in the 'sticks to next' mode, i.e.
make/n=(10,2) tw=p/(q+1)
display tw[][0]; append tw[][1]
ModifyGraph rgb=(0,0,0),mode(tw)=1,toMode(tw)=1

This does not seem to work and I don't know if there is a particular reason for this.
If not I would like this feature to be added to the wish list.

Just today it was reported that toMode does not work for subranged display.

I will try to fix this for 6the .20 release but can't promise it will make it.

Try separate waves rather than columns from the same wave.
