Software to make line graph, Like Excel?

  1. Sep 22, 2007 #1
    Is there any software that will convert a series of numbers into a simple line graph, the same as Excel, but allowing me to use a lot more numbers?

    I'm writing a program in c to convert a sinewave, or any wave, into a triangular wave.
    I've sort of done it, but there is noise in my triangular wave output if the input is of varying frequency, and I don't know for certain why. It is very hard to tell by looking at a page of numbers, so I want to look at a graphical representation of my triangular wave and see what's going wrong. The data, the points on the graph, is too much for excel.

    Thanks
    Tony

    Matlab of course. Not free, though.

    Gnuplot does the trick.
    Matlab - £3,000. The opposite of free!

    Many thanks

    R is open source software and a library called ggplot2 allows you to make publication quality graphs. A bunch of examples are available at http://www.r-chart.com/.
