Plotting multiple series from file using Gnuplot

Question

I've got a data file of the form: Series_1 "12-Dec-2011 12:00" 32 Series_1 "12-Dec-2011 12:01" 29 Series_1 "12-Dec-2011 12:02" 27 Series_1 "12-Dec-2011 12:04" 23 Series_2 "12-Dec-2011 12:01" 45 Series_2 "12-Dec-2011 12:02" 43 Series_2 "12-Dec-2011 12:04" 38 Which I'd like to plot as a number of series on the same plot using gnuplot, but I'm new to gnuplot and I cannot figure out how the using clause should be structured here. I wanted to plot column 2, date/time as the X axis with column 3 as the Y axis, with subsequent sections being overlaid. Is this possible? Surely the X axis doesn't always have to be in the first column? I tried: plot "datafile.dat" using 2:3 title 'Hits' But got the error: x range is invalid Can anyone show me where I'm going wrong?

Expanding @Woltan's answer: if you want each section in a different colour/style, use the index (but then you have to separate sections by two emtpy lines): plot 'i' index 0 using 2:4 with lines, '' index 1 using 2:4 with lines
