-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
when reading the number of points you have in each plot, I have to ask why you need so many (plotted) data points. If you plot e.g. every 10th or 50th data point, you reduce the number of points by a factor of 10 (or 50). This should make the PDF smaller and faster and even if you zoom into each plot, you should be able to see enough details (of course, if there are one or two outliers you might not see them). And probably you are not able to distinguish between two data points if they are too close to each other so you probably don't need every data point.
