Re: [Gnuplot-info] splot and partial data

[Thomas S. <t.s...@fz...>]

you are only plotting one surface and your color specification is
not correct (linecolor rgb "#aabbcc")

you don't need any linecolor, linewidth, title, ... options when 'plotting'
into a table:
splot "data.txt" using 1:2:5, "data.txt" using 1:2:4
is sufficient.

have a look at the 'table' file with a normal text editor - you will
realize that there are isolines for 2 surfaces, separated by a double
linefeed.
and - there are only 3 numbers for each data point - only
'using 1:2:3' will work.

your plot command will have to plot 2 surfaces, selected using the
'index' option:
splot 'tmp2.dat' using 1:2:3 index 0 with lines title "w1s" lc rgb "#005500"
linewidth 2.5, 'tmp2.dat' using 1:2:3  index 1 with lines title "w1"  lc rgb
"#000000" linewidth 2.5


I'm using GNUPLOT 4.2 patchlevel 2 for Windows (32 BIT).
Here is my complete code:

set xrange[4:11];
set yrange [3:*];
set xlabel "r";
set ylabel "d";
set zlabel "sec";
set dgrid3d;
set table 'tmp2.dat';
splot "data.txt" using 1:2:5 with lines title "w1s"  lc rgb "#005500" 
linewidth 2.5, "data.txt" using 1:2:4 with lines title "w1"  lc rgb
"#000000" linewidth 2.5;
unset table;
unset dgrid3d;
set key left;
splot 'tmp2.dat' using 1:2:($1>$2?$3:0/0)  with lines title "w1s"  lc
"#005500"  linewidth 2.5, 'tmp2.dat' using 1:2:($1>$2?$4:0/0)  with lines
title "w1"  lc "#000000" linewidth 2.5;

the output should produce one plot in green and one in black. However, they
are both the same. The data-File is as follows:

4, 3, 0, 0.086000, 0.125000
6, 3, 0, 0.515000, 0.397500
6, 5, 0, 0.374500, 0.296000
8, 3, 0, 2.871000, 1.645000
8, 5, 0, 22.682500, 12.909000
10, 3, 0, 9.391000, 5.679000
