i have function plotted on picturebox, i can zoom it, when graphic are out of picturebox i want with
scroolbars move it or mouse movement to watch part hide of it. everytime i click to scrollbar
i clear picturebox then i add to coordinates of functions the value of scroll and redraw it again. however
i don`t know why picturebox doesn`t clean and show up like the graphic dragging. how do i avoid that.
worked en VB6 but not in NET although i have to wait a while. i want something like autocad, to move draw and
inmediatly i get draw without delay.

thanks in advance
