[scilab-Users] Beginner problem with xs2pdf

[A. Ismael F. Vaz]

Dear Antoine,

Thanks again for the prompt reply. Using you code I obtain exactly the same
figure.

I am an one hour user of SciLab, but it clearly looks like a bug in the
xs2pdf function, and not a video driver problem.

I guess it is because a figure if obtained by plotting line segments between
the provided function points (linear interpolation). Somehow the driver
(xs2pdf) gets messed with the provided points and from time to time it plots
a line using the first point and not the previous point, which gives the
figure I had attached in the previous message.

Best,
Ismael
