Matplotlib hexbin - get bin borders
I'm wishing to do something similar for small hexbins, thinking to:
(1) Get the hexbin centres: 
    hexobj_cen=hexobj.get_offsets()
    lon_hex=hexobj_cen[:,0]       #hexbin lon centre
    lat_hex=hexobj_cen[:,1]      #hexbin lat centre
(2) Run a for loop (for each hexbin centre) to find the Cartesian distance (N.hypot) between that centre from all points put into an array
Then ask if for each hexbin centre, point-hexbin distance is greater than some maximum distance (half the distance between two opposing vertices.
Great if there is a standard way (within pylab.hexbin) to do this, but also couldn't yet find it.
Is there a way to get the borders of a matplotlib.pyplot.hexbin plot?
Say, i have a pd.DataFrame with spatial latitude and longitude values, which i plot in a hexbin plot. Afterwards i want to assign the corresponding bin of the hexbin grid to each instance of my DataFrame, by checking if the latitude and longitude values of an instance fall in one of the hexbin bins. 
Can i assign names or indices to the different bins?
I have already looked in the documentation for the hexbin plot, all i can find are line properties, which describe the lines that are drawn in the plot.
