Hi Mihai,

Thanks for a great repo 👍 I am working my way through it.

I just wanted to point out a few small issues:

data=data.replace('-999.00000',np.nan) is not correct and doesn't work it should be
data=data.replace(-999.00000,np.nan) because the values get imported as numbers you can check this by running data.dtypes

Also I'm not sure why you are specifying the index at the import because then the later rename lines don't make sense. I would do it like this:

data=pd.read_table('WA1.txt', delim_whitespace=True)
data=data.replace(-999.00000,np.nan)
data=data.rename(columns=({'M__DEPTH':'DEPT'}))

I would leave it at this since i prefer using the default index, but if you really want then you can set the index to be the DEPT column.

data.set_index('DEPT')

hope this makes sense, thanks again

when you define the vclgr function in the section In [15], the function parameters are gr_log, gr_clean, gr_clay, of course you declare them in the section In [23]: gr_clean, gr_clay, etc. My question is where do you declare gr_log, sp_log, neut_log, etc.?

after i try run the program until

triple_combo_plot(data.DEPT.min(),data.DEPT.max())
the result only well composit with nothing inside. only the square line and title "well composite. because "NameError: name 'ax' is not defined" appear. could you help? because im new to programming.
