[ferret_users] Irregular depth from delimited file

[Karnan C <karnanc6@xxxxxxxxx>]

Dear ferret users,
I have to generate a time series vertical plot of nutrient or any data.
In which I need y=depth and x=collection dates/numbers.
My delimited data set contains 5 columns such as depth, collection,
data1, data2, data3.
My collection is regular from 1 to 18 but the depths of each
collection were irregular.
I have tried with some earlier queries and methods.
I can define time axis (regular), but I can't find a solution for
depth (irregular).
Kindly help me.

Thanks
My data is attached here.

I have followed these methods,


yes? FILE/FORMAT=DELIM/type=numeric/SKIP=1/VAR="a1,a2,a3,a4,a5" M1_Ratio.csv
yes? sh da

Help me to solve this issue.
