[Gnuplot-bugs] splot with trig functions

[Matthew B. <ma...@ma...>]

I am pretty (3 sigma) sure i found a bug w/ both the 4.2RC1 and 4.0 gnuplot.

It seems to ignore the variation in y when i do this plot (sin too). 
However, if i just plot cos(x/2) it works right. Is there something that 
i am doing wrong here(is gnuplot making an assumption of something not 
obvious)??  This should look like a surface of the 1D plot.


gnuplot> set yran [-pi:pi]
gnuplot> set xran [0:1]
gnuplot> spl cos(y*(1/2))
Warning: empty z range [1:1], adjusting to [0.99:1.01]

Thanks
