tj / histo Goto Github PK

Hi, I like the idea of histo very much, although I can't get it to work properly. It only outputs weird characters on my terminals (iTerm2). Like this:

2;20;f█-53;20;f█-54;20;f█-55;20;f█-56;20;f█-57;20;f█-58;20;f█-59;20;f█

Any idea what is wrong?

needs to carry over back to the left, and we need to indicate old values with light gray shaded blocks or similar

Hi, so there is a somewhat serious problem here. If x is the value, m is the max value in our input file, mb is the number of blocks (the character used to generate the bars) associated with m for a given window size, and xb is the number of blocks associated with x for the same window size, we want that

x/m = xb/mb

However, if m=6, x=1, and mb=100, we can't satisfy xb with an integer value. As the window size gets smaller, this issue becomes more apparent (you'll sometimes have 4 blocks for the value 1, but 9 blocks for the value 2). There are a couple possible solutions to this issue, but I'm not sure which approach is best, so I'd like your thoughts:
-have variable sized blocks for the very top block (not sure how we would do it, as currently our blocks are a char)
-have variable y-padding, again to try to make this equation hold with integers
-use some kind of fill/paint that just colors a region entirely

Hey! This is gorgeous and amazing. Thoughts on a formula for homebrew?

Something like this:

require 'formula'

class Histo < Formula
  homepage 'https://github.com/visionmedia/histo'
  url 'https://github.com/visionmedia/histo/tarball/0.0.1'
  sha1 '3398f6d94bdbdb6f0112e77b61d9c2d6ae1facd1'

  def install
    system "make install"
  end
end

This seems to generate a single bar for every data element in the input file, essentially a bar graph generator. A histogram buckets the data into groups (0 - 10 == bucket 1, 11 - 20 == bucket 2, etc) and then plots bars for every bucket giving you a idea of the distribution of the values in your dataset.

Hi,

Any chance you could rescale the x-axis so negatives are below. I like your implementation, but shading in negative values just isn't cool.
