[Gnuplot-info] using variable values in legends

[Nicolas B. <nb...@la...>]

Hi,

I would like to use the actual values of fitting variables in my 
legends. I can't figure out how that would work though. Naively I would 
expect that something like the following would do the job:

f (x) = a + b * x + c * x**2
fit f (x) 'test.dat' via a, b, c

plot 'test.dat' title 'data', \
	f (x) title 'f (x) = $a + $b * x + $c * x**2'

so that ${a,b,c} will be replaced in the actual title with their 
respective values. Is it possible at all to print variable values 
instead of their names? I can't find anything in the documentation 
files and an online search didn't reveal anything either.

	Thanks already, nick
