[Gnuplot-py-users] Newbie question

[Johan E. <ekh...@gm...>]

Hi all,
I'm trying to make my first plot using Gnuplot.py.
I'm using scipy and numpy and I have issued the following commands in my
script:


import Gnuplot

x = linspace(0.0, 1.8, 18)
y = 3 - 2*x + 2*sin(4*x)
points2 = transpose(array([x,y]))

g = Gnuplot.Gnuplot(persist=1)
d = Gnuplot.Data(points2, with='linespoints', title='points2')
g.plot(d)


However, the plot consists of only one point, even though the vectors x and
y look as I expect.
I also get the following message:

In [3]: Warning: empty x range [0:0], adjusting to [-1:1]
Warning: empty y range [3:3], adjusting to [2.97:3.03]
gnuplot_x11: Some character sets not available


Does anyone know what I'm doing wrong?

Best regards,
Johan
