Command-line Unix ASCII-based charting plotting tool

Question

Is there a good command-line UNIX charting   graphing   plotting tool out there   I m looking for something that will plot xy points on an ASCII graph   Just to clarify  I m looking for something that will output a graph in ASCII  like ascii-art style   so I can use it over an interactive shell session without needing X

You should use gnuplot and be sure to issue the command "set term dumb" after starting up. You can also give a row and column count. Here is the output from gnuplot if you issue "set term dumb 64 10" and then "plot sin(x)":

 

    1 ++-----------****-----------+--***-------+------****--++
  0.6 *+          **+  *          +**   *      sin(x)*******++
  0.2 +*         *      *         **     **         *     **++
    0 ++*       **       *       **       *       **       *++
 -0.4 ++**     *         **     **         *      *         *+
 -0.8 ++ **   *     +      *   ** +         *  +**          +*
   -1 ++--****------+-------***---+----------****-----------++
     -10           -5             0            5             10

It looks better at 79x24 (don't use the 80th column on an 80x24 display: some curses implementations don't always behave well around the last column).

I'm using gnuplot v4, but this should work on slightly older or newer versions.

Another simpler lighter alternative to gnuplot is ervy  a NodeJS based terminal charts tool   Supported types  scatter  XY points   bar  pie  bullet  donut and gauge   Usage examples with various options can be found on the projects GitHub repo

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 PDF   An example of use       gt  git shortlog -s -n   awk   print  1     eplot 2 gt   dev null     3500   ------- ------- -------- -------- ------- -------- ------- -------                                      tmp eplot20121012-19078-fw3txm-0                                                                                         3000                                                                                                                                                                                                                                   2500                                                                                                                                                                                                                                     2000                                                                                                                                                        1500                                                                                                                                                                                                                                      1000                                                                                                                                                                                                                                       500                                                                                                                                                                                                                                         0   ------- ------- -------- -------- -----                                     0        5       10       15       20      25       30      35       40

Check the package plotext which allows to plot data directly on terminal using python3  It is very intuitive as its use is very similar to the matplotlib package   Here is a basic example     You can install it with the following command   sudo -H pip install plotext     As for matplotlib  the main functions are scatter  for single points   plot  for points joined by lines  and show  to actually print the plot on terminal   It is easy to specify the plot dimensions  the point and line styles and whatever to show the axes  number ticks and final equations  which are used to convert the plotted coordinates to the original real values    Here is the code to produce the plot shown above   import plotext plot as plx import numpy as np  l 3000 x np arange 0  l  y np sin 4 np pi l np array x   np exp -0 5 np pi l x   plx scatter x  y  rows   17  cols   70  plx show clear   0      The option clear True inside show is used to clear the terminal before plotting  this is useful  for example  when plotting a continuous flow of data   An example of plotting a continuous data flow is shown here     The package description provides more information how to customize the plot   The package has been tested on Ubuntu 16 where it works perfectly  Possible future developments  upon request  could involve extension to python2 and to other graphical interfaces  e g  jupiter   Please let me know if you have any issues using it  Thanks    I hope this answers your problem

gnuplot is the definitive answer to your question   I am personally also a big fan of the google chart API  which can be accessed from the command line with the help of wget  or curl  to download a png file  and view with xview or something similar    I like this option because I find the charts to be slightly prettier  i e  better antialiasing
