Hi, I've created a small script to do bar-graphs for a period ofd 1 week (1 number per day...)
Ive got 5 days worth of data now - & in a few days the 1st day (inly partial data so its a lot lower in volume than the rest...) The problem, is that in a few days, i'm going to have (virtually) a straight-line with little movement in the bar-graph heights.... BACKGROUND TO CALCULATION :- basically ive got this... $maxnumber $minnumber $val=((($value-$minnumber)/$value)*100); QUERY... I thought of that while I was at work today - (ive got home now - will test.. & think of something ) The above formulae does work in theory however the lowest value will always be at 0% of the graph Is there a small calculation, so the lowest value for the week will be at 10% of the graph, & the other values will be relative to the figures ? (Ie you can easily see the differences..) -- G NZ community groups - [EMAIL PROTECTED] Freecycle Auckland :- http://groups.yahoo.com/group/AucklandFreecycle/
