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 gnuplotpy?  Richard Langley   Richard B. Langley Email: lang@...
