pgf error maths

Question

help me please:

I don't understand why pgf show me this error, for all my dates:

Package PGF Math Error: Could not parse input '14.099117,3.068e+6,' as a floating point number, sorry. The unreadable part was near ',3.068e+6,'.. \addplot[color=black] file{dicloro.txt};

this is my archive:

Answer 1

I think pgfplots assumes that columns in data files are separated by a space by default, and you seem to have comma separated columns. Try using

\addplot[color=black] table[col sep=comma]{dicloro.txt};

instead of \addplot[color=black] file{dicloro.txt};.

This will by default use the first column for the x-values, and the second column for the y-values.
