But to my current issue: I wish to plot the vector field of a 1st order ODE. Grapher certainly seems capable of this (and much more), as the examples show, but my fields always end up with each vector either pointing straight up or straight down, and all their lengths the same. Their colours seem to correlate with each vector's relative magnitude but this, while pretty, is not as legible as varying the length of the vector.

Note this is Grapher V1.0 on Tiger. Perhaps things have changed in Leopard. [...]

My strong impression is that Grapher has been completely abandoned by Apple. I'm not aware of any bug fixes or improvements that have been made since it was first released. Given that, my feeling is that trying to learn to make practical use of it is likely to be a frustrating and unrewarding experience.
