Hi all, I'm writing script in python, which fitting exponencial curve to data ( f(x) = a*exp(x*b). To this problem, I use gnuplot in my script. Gnuplot display parameters ( a +/- delta a; b +/- delta b) How Can I use/save this parameters in python variables in next steps of my script, def main(): ... plot = Gnuplot.Gnuplot() plot('f1(x) = a1*exp(b1*x)') plot('a1 = 300; b1 = 0.005;') plot('fit f1(x) "data.txt" using 1:2 via a1, b1') print "first parameter", a1 print "second parameter", b1 # is it feasible ? Or there is another way to see the results ( parameter a1 and b1) of gnuplot by python #plot('set terminal postscript') #plot('set output "output.ps"') regards and please help, Cristopher |
