Line graph animation

[Filip Vandueren]

You would start with a dataset, like a .csv.

Then to draw the line; this expression on a Path should get you started:

w=1600;
pts=[];
endF=1+timeToFrames(time);
for (i=0; i<=endF; i++) {
    data = parseFloat(footage("data.csv").dataValue([1,i]));
    pts.push([i*(w/endF),data]);
}
createPath(pts,[],[],false);

That will draw a line, that gets a new datapoint every frame from column 2 of data.csv, but the total width will always be 1600 pixels.
