Niklas, if you have Excel at your disposal, the best way kof demonstrating what I mean is sending you an Excel workbook and an OO sheet with the same example which clearly shows what the problem is.
I will describe a minimal example. Put 0.4 in A1 Put the numbers from 0 to one in steps 0f .1 in A3 to A13 in B3 enter the formula =(A3-$A$1)^2 and copy it down from B4 to B13. now, create an x-y-plot for the range A3:B13 (with connected points). You get the graph of a quadratic function. Fix the y-axis for a range from 0 to 1. Connect a scrollbar with cell B1, and let the scrollbar produce values from 0 to 100. In A1, enter =B1/100 Now move the scrollbar. In Excel, you get smooth animation, the graph moves immediately when the scrollbar moves. In OO, the graphics change MUCH too late to call this animation. I am producing a lot of effects this way, I think it is the easiest way of getting animated graphics in any program. If I can get this in OO, I will consider switching part of my teaching to OO. Without it, I cannot switch.
