Plotting bug?



Hi Everyone,

I find a funny thing happening when I plot with this command:

plot2d([realpart(ev(sum(%e^(-2*%i*%pi*f*k),k,-50,50),simpsum))], [f,-2,2],[y,-50,50]);

The problem is that certain ranges give constant and incorrect values on
the plot.  I can send a screenshot to anyone interested.  If I change
the f plot range, the blanks disappear and it works.  It also works
sometimes for different numbers of terms in the sum.   Where
should I report this bug?  If I am the best person to try and figure it
out, is there a debugger or something I can use to trace what is
happening in the plot command?

Thanks,

Rob
