I’m working with Cartesian coordinates and some of the coordinates can get into pretty large numbers so I would like to scale them from metres to kilometres (i.e. divide by a 1000). I did think about rescaling my data’s coordinates, but it gets tedious with many layers, and it’s really just the plot annotations that I need to scale.

Current:

```
fig = pygmt.Figure()
fig.basemap(region=[100000, 500000, 600000, 900000], projection="X7c", frame=True)
fig.show()
```

Desired:

Actually had a look at the map frame options in gmt — GMT 6.5.0 documentation but couldn’t work out how to do it, or if it’s actually possible. Anyone who can point me in the right direction?
