plot_ppi_map() throwing "QuadMesh.set() got an unexpected keyword argument 'add_grid_lines'"

[kylejgillett]

• Py-ART version: 1.15.0
• Python version: 3.9.16
• Operating System: Windows

Description

Since recently updating pyart, I am getting the attribute error "QuadMesh.set() got an unexpected keyword argument 'add_grid_lines'" when trying to use the same plot_ppi_map() I had been using prior to updating. I am attempting to set add_grid_lines to false.

Just a side note, I have also been making updates to other packages recently too, not sure if that would be involved.

I see in the traceback that add_grid_lines is not included in the kwargs, but it's still up on the docs: https://arm-doe.github.io/pyart/API/generated/pyart.graph.RadarMapDisplay.plot_ppi_map.html#pyart.graph.RadarMapDisplay.plot_ppi_map

What I Did

CODE:

display.plot_ppi_map('reflectivity',
                     sweep=0,
                     ax=map_ax,
                     vmin=-20,
                     title_flag = False,
                     colorbar_flag = False,
                     cmap='pyart_LangRainbow12',
                     resolution='10m',
                     gatefilter=gatefilter,
                     vmax=70,
                     lat_lines=None, 
                     lon_lines=None,
                     add_grid_lines=False,
                     zorder=2)

TRACEBACK:

@kylejgillett Thanks for letting us know! I am unable to reproduce this error - can you run a conda list command to double check with versions of packages are being used here?

[zssherman]

@kylejgillett, were you still encountering this issue?

[kylejgillett]

Hey! Apologies for the delayed response. I had to completely rebuild my conda environment a while back and since then, I am no longer running into this issue, so I assume it was something related to out-of-sync versions of various packages.

[zssherman]

@kylejgillett No worries at all! And sounds good, glad to hear you got it working! I'll close the issue for now.
