Hi -- I've been a long-time user of gnuplot, but am baffled at why it's consistently ignoring the first line from all my data input files? I am using the current release version, 4.4.0. My data file is: 50534 0.01 2048 4 2 1 42331740.77 50534 0.01 2048 4 2 1 42331740.77 50534 0.1 2048 4 2 1 148496233.59 50534 0.25 2048 4 2 1 183645787.30 50534 0.5 2048 4 2 1 206525421.53 50534 0.90 2048 4 2 1 242512603.37 My gnuplot command script is where I just want to plot the 2nd column as X and 7th column as Y. Any ideas -- my script is below?? Thanks, Chris ################################################### set border 3 set terminal postscript portrait size 8,8 font "Times,14" set size square set style data linespoints set key inside right top Left reverse enhanced autotitles nobox set key bmargin center horizontal Left reverse enhanced autotitles columnhead box set key samplen 4 spacing 1 width 0 height 0 set ylabel "Event Rate" set xlabel "Lookahead" set xrange [0.0:1.0] # set logscale x set xtics (0.01, 0.10, 0.25, 0.5, 0.90) # set xtics (1, 10, 25, 50, 90) ########################################################################################### # 1K event rate ########################################################################################### set output "event-rate-1K.eps" set title "1024 Processor Performance" plot "data-files/event-rate-1K-optimistic-no-stagger.data" using 2:7 title "Opt/No-Stag" |

When I remove the copy of the first line, it disappears .. What you have it my hack to get it to appear .. just copy the first line twice in the data file .. It appears to have the same behavior on gnuplot 4.2.5 ... Any ideas?? Thanks, Chris 2010/6/15 Hans-Bernhard Bröker <HBB...@t-...> > Christopher D.

if you define set key autotitles columnhead the first data line is used for setting the title, so it's not used for plotting. you would have seen this if you would have let gnuplot set the title automatically, instead you specified an explicit title as option for the plot command.

What is the smallest file that shows this behavior? For instance, if you have the file containing ONLY: 1 2 3 does it gobble up the 1 and the 3? I wonder whether your problem is something weird having to do w/ file formats - such as taking a file from one platform and trying to read it on another. Best, Ph.
