Command-line Unix ASCII-based charting / plotting tool
Try gnuplot. It has very powerful graphing possibilities.
It can output to your terminal in the following way:
gnuplot> set terminal dumbTerminal type set to 'dumb'Options are 'feed 79 24'gnuplot> plot sin(x) 1 ++----------------**---------------+----**-----------+--------**-----++ + *+ * + * * + sin(x) ****** + 0.8 ++ * * * * * * ++ | * * * * * * | 0.6 ++ * * * * * * ++ * * * * * * * | 0.4 +* * * * * * * ++ |* * * * * * * | 0.2 +* * * * * * * ++ | * * * * * * * | 0 ++* * * * * * *++ | * * * * * * *|-0.2 ++ * * * * * * *+ | * * * * * * *|-0.4 ++ * * * * * * *+ | * * * * * * *-0.6 ++ * * * * * * ++ | * * * * * * |-0.8 ++ * * * * * * ++ + * * + * * + * * + -1 ++-----**---------+----------**----+---------------**+---------------++ -10 -5 0 5 10
While gnuplot is powerful, it's also really irritating when you just want to pipe in a bunch of points and get a graph.
Thankfully, someone created eplot (easy plot), which handles all the nonsense for you.
It doesn't seem to have an option to force terminal graphs; I patched it like so:
--- eplot.orig 2012-10-12 17:07:35.000000000 -0700+++ eplot 2012-10-12 17:09:06.000000000 -0700@@ -377,6 +377,7 @@ # ---- print the options com="echo '\n"+getStyleString+@oc["MiscOptions"] com=com+"set multiplot;\n" if doMultiPlot+ com=com+"set terminal dumb;\n" com=com+"plot "+@oc["Range"]+comString+"\n'| gnuplot -persist" printAndRun(com) # ---- convert to PDFAn example of use:

Another option I've just run across is bashplotlib. Here's an example run on (roughly) the same data as my eplot example:
[$]> git shortlog -s -n | awk '{print $1}' | hist 33| o 32| o 30| o 28| o 27| o 25| o 23| o 22| o 20| o 18| o 16| o 15| o 13| o 11| o 10| o 8| o 6| o 5| o 3| o o o 1| o o o o o 0| o o o o o o o ---------------------------------------------| Summary |-----------------------| observations: 50 || min value: 1.000000 || mean : 519.140000 ||max value: 3207.000000|-----------------------Adjusting the bins helps the resolution a bit:
[$]> git shortlog -s -n | awk '{print $1}' | hist --nosummary --bins=40 18| o | o 17| o 16| o 15| o 14| o 13| o 12| o 11| o 10| o 9| o 8| o 7| o 6| o 5| o o 4| o o o 3| o o o o o 2| o o o o o 1| o o o o o o o 0| o o o o o o o o o o o o o | o o o o o o o o o o o o o --------------------------------------------------------------------------------
