Hi All, I am trying to set a title on the legend based on data from multiple columns. for instance the file name is out.txt: #N m C b A B STDEV_A STDEV_B 100000 1 0.1 0 0.020280 0.232320 4.457500E-04 1.335500E-03 1000000 1 0.1 0 0.020740 0.232260 1.425000E-04 4.222800E-04 10000000 1 0.1 0 0.020800 0.231650 4.512800E-05 1.334100E-04 100000000 1 0.1 0 0.020740 0.231890 1.425300E-05 4.220400E-05 I am plotting using the following: set log x set xrange [ 10000 : 1000000000] set title "Albedo" plot "OUT.txt" index 0 using 1:5:7 title column(2) with yerrorbars 3 This works, but I am having a difficult time combining say column 2, 3, and 4 as in "m = ".column(2)." C = ".column(3)." b = ".column(4) Does anyone have any idea?

your plot command doesn't really work because you loose the first line, due to the columnheader(2) option which interprets the first line as a text line, not as a data line. a 'plot nothing' to set a variable containing the values you want to have in the key should do the job: plot "OUT.txt" using \ 0:(my_title="m = ".stringcolumn(2)." C = ".stringcolumn(3)." b = ".stringcolumn(4) , 0/0) \ every ::0::0 notitle, \ "" index 0 using 1:5:7 title my_title with yerrorbars AceStrider1 wrote: > > Hi All, > > I am trying to set a title on the legend based on data from multiple > columns. > > for instance the file name is out.txt: > > #N m C b A B STDEV_A STDEV_B > 100000 1 0.1 0 0.020280 0.232320 4.457500E-04 1.335500E-03 > 1000000 1 0.1 0 0.020740 0.232260 1.425000E-04 4.222800E-04 > 10000000 1 0.1 0 0.020800 0.231650 4.512800E-05 1.334100E-04 > 100000000 1 0.1 0 0.020740 0.231890 1.425300E-05 4.220400E-05 > > I am plotting using the following: > > set log x > set xrange [ 10000 : 1000000000] > set title "Albedo" > plot "OUT.txt" index 0 using 1:5:7 title column(2) with yerrorbars 3 > > > > This works, but I am having a difficult time combining say column 2, 3, > and 4 as in > "m = ".column(2)."

Thomas,
Thank you very much for the prompt reply and suggestion. Your method seems
to work at concatenating. It is correctly reading the values from the
columns. The only strange thing now is that gnuplot in now using the first
line of my last group (index 79) instead of (index 0).
For Instance my datafile out.txt looks like:
#NPARTICLES m C b A B STDEV_A
100000 1 0.1 0 0.020280 0.232320 4.457500E-04
1000000 1 0.1 0 0.020740 0.232260 1.425000E-04
10000000 1 0.1 0 0.020800 0.231650 4.512800E-05
100000000 1 0.1 0 0.020740 0.231890 1.425300E-05
100000 5 0.1 0 0.021760 0.001920 4.613800E-04
1000000 5 0.1 0 0.021780 0.002020 1.459800E-04
10000000 5 0.1 0 0.021670 0.002070 4.604500E-05
100000000 5 0.1 0 0.021690 0.002050 1.456700E-05
100000 10 0.1 0 0.021710 0.000020 4.608600E-04
1000000 10 0.1 0 0.021570 0.000010 1.452900E-04
10000000 10 0.1 0 0.021710 0.000010 4.608800E-05
100000000 10 0.1 0 0.021680 0.000010 1.456300E-05
100000 20 0.99 4 0.767610 0.013350 1.335600E-03
1000000 20 0.99 4 0.770680 0.013310 4.204000E-04
10000000 20 0.99 4 0.769150 0.013460 1.332500E-04
100000000 20 0.99 4 0.769360 0.013440 4.212400E-05
So I am plotting the correct data, except the labels are off. I confirmed
it was the first line of my
last index group by changing 0.99 to 0.79 and plotting.
This is what my gnuplot file looks like now:
reset
set terminal svg
set output "CASE0.svg"
set xlabel 'Particles'
set ylabel 'Fraction'
set grid
set log x
set xrange [ 10000 : 1000000000]
set title "Albedo"
plot "OUT.txt" using 0:(my_title="Analog m = ".stringcolumn(2)." C =
".stringcolumn(3)." b = ".stringcolumn(4) , 0/0) \
every ::0::0 notitle, "" index 0 using 1:5:7 title my_title with yerrorbars
3
set terminal wxt
replot
I believe every ::0::0 means to use the first line only.
I am not so sure about 0/0 <-- it did not seem to make a difference if I had
it in there or not.
Thanks Again,
Adan

oh, i forgot the 'index 0' in the dummy plot: plot "OUT.txt" using \ 0:(my_title="m = ".stringcolumn(2)." C = ".stringcolumn(3)." b = ".stringcolumn(4) , 0/0) \ every ::0::0 index 0 notitle, \ "" index 0 using 1:5:7 title my_title with yerrorbars yes, 'every ::0::0' means the 1st line of a data set. '0/0' means 'undefined', and undefined points are not plotted. AceStrider1 wrote: > > Thomas, > > Thank you very much for the prompt reply and suggestion.
