river plots #48
Description
implement plotting variables such as composition at the surface of the model as a function of time (images like in gurnis 1988 fig. 6): how to implement: e.g. stagpy field --iz=nz --s=0:30 -o c +river gives river plot of concentration at the surface as a function of time
first, we could generalize the field command to plot horizontal or radial slices. That would remove the need for a zoom option, allow the user to plot local profiles, and pave the way for handling 3D geometry by allowing plotting arbitrary slices.
The river stuff could come on top of that as an option that only makes
sense with a set of 1D profiles taken over several timesteps.
note: for the zoom plot:
- zoom is around a rectangle (specified by its centre and size)
- could have a plot of field with a grid so that people can easily know how to specify the rectangle
- show the zoomed area in the field plot
