Description of the desired feature

Right now, the MAP_LABEL_OFFSET option for placing the axis label text is set to be relative to the side of the annotations. For stacked plots (e.g. a stack of time series), this can lead to the problem of the labels not being aligned on all of the plots if the annotations are of difference sizes. Ideally, an option to set the MAP_LABEL_OFFSET to be relative to the axis rather than the annotation would make it easier to line things up.

To illustrate what I mean, I have attached this image. As you can see, the label “Sliding Mechanism” is much further to the left of the other labels.

There is some further discussion on the GMT forum

As mentioned in the post, the workaround for now is to use gmt text -N.
