Many times, we need nice figure to show our data. In general, Origin is good enough for me (I am a PhD student now), but some I want some more beautiful graphs. Herein, I note same software here. Prism, a origin-like tool http://www.graphpad.com/scientific-software/prism/#7 canvas X http://www.canvasx.com/en/support/canvas-11 irfanview http://www.irfanview.com/ A very useful tool to compress figure. gnuplot http://www.gnuplot.info/ I usually use origin to plot my figures. But it is a not free software and has not mac version. Gnuplot is small and command line based, and I think that it may be a good tool to complete my figures.
