update plot_bdy.py: Plot 1D variables

[jpolton]

Plotting routine that show variables for the extracted boundaries needs updating to accommodate 1D variables (e.g SSH) to compliment 2D depth sections.

Basically I abstracted the existing 2D section plotting code into a method and wrote a partner method for 1D variables.

AC: To test, first need to create suitable output. E.g.

namelist_local.bdy: Edit:
line 59:  ln_dyn2d       = .true. # as in this branch (we may not want to merge this edit to master)

Then generate surface data from benchmark datasets:

pybdy -s /inputs/namelist_local.bdy

Execute plotting script on this output: python plotting/plot_bdy.py outputs/NNA_R12_bdyT_y1979m11.nc sossheig

• [ ] Should make a image like:

NB: There is much to do to improve this plotting routine. There is a list of suggestions in the file header:

To do:

• labelling of plots : Add variable name
• Which segment is where? Add x-axis label could be bdy index?
• Not sure why sometime tmp.png (bdy index on map) is plotted and sometime not

These will go in a ticket for future work
