The method I used for ascii graphs was based on some C program I wrote that created an array, which was, in essence, the graph. Each array element was two characters wide (we''l see why..) The first column of the array is all |, to make a Y axis, and the last row if the array is all _, to make an X axis. Then there were two other arrays, for labels, that were stuck along side or below the axes (dynamic). The first array is modified based on the data, using O, -, |, \ and / in goofy combinations to draw lines. Then I characterized characters (heehee) as either wide, or narrow, to avoid width problems, and when it's a "narrow" character you insert a space to avoid problems with lines not lining up. Then, spit the array out to the display. Whheeeee fun. We should have an "ASCII/PHP/Database Graphing Contest." I'll host it if there are interested contestants. Suggested design: HTML form for data input, passes to PHP script for immediate (and STYLIN') ascii output. Any takers? Will post the code/output example when I have a free moment...
