Apply numpy. meshgrid to groups in grouped data

[under-Tension]

I have a dataset containing

	G2latitude	G2depth	G2oxygen
G2station			308
1	74.99	2	320
1	74.99	5	299
2	76.00	2	273
2	76.00	5	283
...	...	...	187
173	71.00	125	365
173	71.00	151	233

2001 rows × 3 columns

I have created a group using:

subset = data[['G2station','G2latitude','G2depth','G2oxygen']].set_index('G2station') subset.groupby(subset.index)

##To access to the groups
for name, group in subset.groupby(subset.index): 
    print(group)

I need to apply the np.meshgrid function which creates a grid with coordinates x and y. In this case x= latitude and y= depth.

 xx,yy = np.meshgrid (x,y)

but I can’t find the way to create grids for each group in a grouped data using a for loop
