[Gnuplot-info] Multiple string concatenation after title using column(n) function

[AceStrider1 <Ace...@ya...>]

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?

Thank,
Adan
