[Gnuplot-py-users] Passing the Value of a Variable to Gnuplot-py

[Richard L. <la...@un...>]

In a Python script, I compute the value of a variable. Let's call it cep. I then want to draw a circle whose radius is cep. I would like to have something like

cep = (some calculation producing a float value)
g('set parametric')
g('set trange [0:2*pi]')
g('fx(t) = cep*cos(t)')
g('fy(t) = cep*sin(t)')
e = Gnuplot.Func('fx(t),fy(t)')
g.plot(e)

but that doesn't work, it seems, as gnuplot doesn't know the value of cep ("undefined variable: cep"). So how does one pass an arbitrary variable value to gnuplot-py?
