Hi Ignasi,
your analysis is correct: pgfplots reads only the first two columns in
order to plot the data whereas
\pgfplotstabletypeset[header=false]{sin3.dat}
attempts to process the complete table. Since it expects *numerical* cell
content, it fails to typeset the third column . Although I would have expected
a better error message...
Your approach to explicitly select the desired columns is the solution.
Best regards
Christian

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
