I am looking to create a plot similar to the one above but in QWT. I tried inheriting from the QwtScaleDraw class and then implementing the draw label but that only draws the label for the specified tick mark. I want to have buckets essentially and only the uppermost bucket correspond to the tick mark. I looked and found a post that looked promising but the class that was being referred to does not exist in the current Qwt version nor does any documentation exist for it. The link to the post that could have been potentially helpful is : https://www.qtcentre.org/threads/690...Plot-multiaxes
