Hello,

Are you manually typing in a 'plotfield' command? Or using the little popup editor that appears when you press the Plot->slopefield in your plot view?

If you don't see a little editor when you do that, that means you aren't up to date in your Prime software. I ask because the editor screen automatically adds in the required 'normalize' tag at the end to give you what you'd like here.

plotfield(sin(x),[x = ((-16.) .. 16.),y = ((-11.) .. 10.9)],xstep = 2.5,ystep = 2.5,'normalize') <-- note the 'normalize' as the last argument.
