Recently I was thinking that I searched a lot of times (when starting programming, a year ago) a canvas control a bit more extended that this we can find in Delphi Libraries. I thought now that your TSimpleGraph works I-think-very-well, the canvas itself, (With the Zoom, The arranges of memory, The ScrollBars options and many more); and that the canvas could be separate from the Chart-compontent (Eliminating the TGraphObjects and any unnecesary procedures). I think that many people would be grateful to find a this-kind of canvas-control. Maybe there's a lot of people that looks for (how I did in the past) a Extended canvas of this kind but they don't found. (ahh, I did once, but it was not a free control). What do you think?
