psxy -Sq: is it possible to not draw a line without play with clipping and transparency?
Sometimes you just need to draw labels along the specified path. This can easily be done by clipping, but why use two commands, if you can use only one? Should I make a feature request for this?
You basically mean an invisible line (since the line is needed to determine where labels are placed). I cannot recall if we every implemented that but I think it is possible. Maybe add a +h modifier to -Sq for hidden line? if this is what you mean then please turn this into a feature request. Meanwhile, depending on background you may work around this by specifying a white pen.
Yes, invisible line. I create a feature request #1207.
