Hello folks, long time no see. http://piratepenguin.is-a-geek.com:82/~declan/algebra/testing.xhtml ^ View in an SVG-enabled browser. There are a few fucked up things about that document, but my work is incomplete since I'm stumped as to in what way I should label and mark units on the axes. I've implemented different methods to do this about 2 or 3 times, and none have impressed me over a wide enough scope of zoom levels. I am only dealing with the positive X axis until I get this right 100%. I want to be able to deal with users viewing 5, 10, 100, 1000, and then 1 and under units there, and at intervals there needs to be marks - some labeled with a figure for the X value, elegantly, and that's the difficult part. Zoom in one in the testing.xhtml setup for the first issue with my current once-looking-promising implementation. Given is the length of one X unit (could be 1px, could be 50px, hopefully could be 5000px), what would YOU do with that unit. I'm hoping somebody has done something a lot like this before, and could give me some tips.
