How to draw 1000+ Graphs and maintain smoothness

up up ↑ ↑

You'll have to give us more information if you want a useful reply. By smoothness, do you mean smooth curves or is this some sort of animation and you want equal time spacing? Is this 1000 separate plots, or 1000 curves on a single plot? Where does the data come from, a file, a measurement instrument,...?
