gnuplot plotting multiple line graphs
I think your problem is your version numbers. Try making 8.1 --> 8.01, and so forth. That should put the points in the right order.
Alternatively, you could plot using X
, where X is the column number you want, instead of using 1:X
. That will plot those values on the y axis and integers on the x axis. Try:
plot "ls.dat" using 2 title 'Removed' with lines, \
"ls.dat" using 3 title 'Added' with lines, \
"ls.dat" using 4 title 'Modified' with lines
andyras is completely correct. One minor addition, try this (for example)
plot 'ls.dat' using 4:xtic(1)
This will keep your datafile in the correct order, but also preserve your version tic labels on the x-axis.
