Gnuplot has several limitations including complex functions not working for gamma and Bessel functions, commands after a load filename being ignored, error bars not being properly handled in polar/spherical plots, and floating point exceptions occasionally being generated by user defined functions. It also has issues with the nohidden3d option not working for parametric curves, time coordinates wrapping at 24 hours with 1 second precision limiting geographic plots, and only one color palette being active per x11 window.

functionsdonotwork for
complexarguments.
If a command line contains
a load command, then anything on
the line after the load
4#4filename5#5 is ignored
Errorbarsare not handled
properly in polar/spherical
coordinate plot modes.
Floating point exceptions (floating
point number too large/small,
divide byzero, etc.) may
occasionally be generated by user
defined functions.

Limitations of GNUPLOT

5. The 'nohidden3d' option thatis
supposed to exemptindividual
plots from theglobal property 'set
hidden3d' does not workfor
parametric curves.
Coordinates specifiedas
"time"wrap at 24 hours,
andhave a precision
limitedto 1 second. Thisis
in particular alimitationin

handle geographic
coordinates.Only onecolor palette at a
time is activefor any given x11
plot window.
