I use GNUPLOT and PGPLOT for plotting my data in C/C++. But these are ridiculously slow when the data size becomes huge. So I want a plotting library that can give me a fast response even if I plot a million points on it. Any recommendations?

Requirements:

  • It should be freeware.
  • It would be good if it runs on all POSIX systems.
  • It should run at least on CentOS and Ubuntu.
  • Is the library supposed to be free or open source? Which operating systems has it to support? – ComFreek Jul 23 '14 at 11:19

  • I don't think this is possible. I think you are running up against the problem that this is not a tractable problem. because plotting time is linear with respect to number of points. I would be very surprised if GNUPLOT or PGPLOT were not already using the most optimal algorithm. It isn't even parallelisable, unless the data is presorted -- sorting would take longer than plotting. – Lyndon White Jul 24 '14 at 12:03
  • I found ploticus to be an order of magnitude faster than gnu plot for something I was working on a few years ago, but I don't really know the current status. – technosaurus Dec 29 '14 at 20:42
  • @technosaurus Thanks I will check it out. – Vivek V K Dec 29 '14 at 22:33
