I am using Maxima 5.13.0 and trying to plot a function using plot2d. Using the
function "x^2" works fine. However, I tried to plot a normal distribution. I
got the following error:
(%i1) load(distrib);
(%o1) /usr/share/maxima/5.13.0/share/contrib/distrib/distrib.mac
(%i2) f(x):=random_normal(0.2,0.1);
(%o2) f(x) := random_normal(0.2, 0.1)
(%i3) plot2d([%o2],[x,0,1]);
gnuplot> plot [0.:1.]'/home/schmitz/maxout.gnuplot_pipes' index 0 notitle
with lines 3
^
line 0: warning: Skipping data file with no valid points
gnuplot> plot [0.:1.]'/home/schmitz/maxout.gnuplot_pipes' index 0 notitle
with lines 3
^
line 0: all points y value undefined!
(%o3)
This also happens if I try to plot a piecewise function. Simple functions like
sin, cos or similar do work well. The maxout.gnuplot* files contain only the
title of the plot and then thousands of empty lines.
What's going wrong here?
Best regards,
Arne
