#3437 — replotting curves for different values of coefficients

I'm trying to superpose curves for different values of a coefficient.

For example, consider:

a = 1
plot a * x
a = 2
replot a*x
a = 3
replot a*x

This doesn't accomplish what I want, which is to superpose these curves.  This is because a is evaluated at plot time, rather than at the time the plot command is executed.

Any ideas?

This, on the other hand, does work, but isn't what I want to do, since my actual formulas are more complicated:

a = 1
plot a * x
b = 2
replot b*x
c = 3
replot c*x


thanks!

plot for [a=0:5] f(x,a)

plot for [a in "1.3 1.4 1.6 1.9. 2.4"] exp(-(x-a)**2)


in gnuplot >5.1, there are also (respectivley will most likely be in
the next stable release) array variables:

plot for [i=0:5] a[i]*x**2 + b[i]*x + c[i]
