Claim:
A method comprising: obtaining, by a computer system, a plurality of values indicative of characteristics of an underground formation; plotting, by the computer system, the plurality of values on an output device of the computer system, the plotting by: plotting parallel to a first axis a first plurality of symbols where each symbol is indicative of a value of a characteristic of a first portion of the underground formation, location of the first plurality of symbols with respect to the first axis is indicative of a first parameter, and location of the first plurality of symbols with respect to a second axis is indicative of a second parameter distinct from the first parameter; and plotting parallel to the first axis a second plurality of symbols where each symbol is indicative of a value of the characteristic of a second portion of the underground formation, location of the second plurality of symbols with respect to the first axis is indicative of the first parameter, and location of the second plurality of symbols with respect to the second axis is indicative of the second parameter; and wherein location of at least one symbol from each plurality of symbols with respect to the first axis is also indicative of a third parameter, different than the first and second parameters.
