This is of course possible, but very undesirable from my perspective - only a desperate last resort. Not only does it imply manually doing the very kind of thing that plplot does so well, it also opens up the door to real errors. If we let plplot mark of the axes with ticks and then try to label them ourselves, we need to be sure we follow (= code ouselves) the same algorithm plplot uses to decide where to put the ticks, and also that we will always get the transition from fixed to floating pt correct. This sound to me like reinventing the wheel when in the simplest case all that is required is the ability to change position and orientation values (3 numbers) that are at present not accessible from the api interface. I'm not at all complaining about your suggestion. Indeed, the reason for my posting is because I had already thought about a do-it-ourselves approach and therefore wondered if someone else had also either encountered it or was more familiar with the internal plplot workings and would have the expertise to offer a more elegant and robust solution.
