Hey... I've been using grapher for a while... but there are just so many things that irritate me about it. Specifically...
1.) The graph doesn't update while you type. Sometimes I'll forget to hit enter and I'll be wondering for a few milliseconds why it hasn't updated yet.
2.) It's not very good at finding intersections. I think it has something to do with there being no real square roots for numbers less than 0 which probably is what generates the error "no roots". So even though there's clearly an intersection between the two, it doesn't find it. (Specifically... I made a circle, then a diagonal line running through it and asked for the intersection. It just gave an error.)
3.) The scroll ball doesn't zoom in and out on the graph (or manipulate it in any other way for that matter.)
4.) When dragging the graph, it doesn't instantly redraw. It seems like this could easily be solved by having an overscan (so it ends up drawing 9x as much as it has to show... but the result is it can easily be scrolled... and I suppose that could make scrolling with the scroll ball pretty smooth too if they chose to do that. Heck, they could make it smart enough to draw only what it has to first, then fill in the parts it doesn't have to have yet.)
So yeah... this is basically a checklist of what Apple should include in the next version of Grapher. But I'd really rather have them now and it seems like someone else has probably wanted similar features. Anyone able to recommend a graphing program they use in Mac OS X rather than Grapher?
