Ascii histograms and more cool data analysis tools in Python
- bialecki 16y agoVery cool. Does it support horizontal histograms? :P
- devmonk 16y agoa tool to pass stdin to stdout for a set time period. I'm curious what that has to do with data analysis.
- dqh 16y agoIt can be used to take a sample of desired duration from a log file of a running system. When combined with other tools in the collection this would be useful for quick and dirty evaluation of the effect of configuration changes, for example.
- cnvogel 16y agoIf you are into real data analysis on the unix-commandline, including ASCII histograms... and are not afraid of 70s-style forgran programming, you should have a look at PAW; the physics analysis workstation. library/program site: http://cernlib.web.cern.ch/cernlib/ http://cernlib.web.cern.ch/cernlib/ sample session transcript: http://pastebin.com/w8GxRPzU http://pastebin.com/w8GxRPzU This kind of ASCII dumping of data was the standard for a long time, and even in the early 90s, people used things like ASCII terminals (e.g. the wonderful Falcos that could superimpose simple graphics on a "2nd" alternatively shown display page). E.g. have a look at the printout on http://en.wikipedia.org/wiki/Wow!_signal http://en.wikipedia.org/wiki/Wow!_signal , that's most likely a "waterfall" display of received signals on a astronomical radio-telescope with number 0...9, A...Z (or something like that) representing the bin scale. Also gnuplot has useful drivers to dump out ASCII pictures (or, using the XTERM Tektronix graphics capabilities, also line graphics). This even works over a simple ssh-session, so it might even be an advantage if you have to check some data on a distant machine. Or scp the data over, and use Excel ;-) {NO! JUST JOKING!}
