Module `Text_graph`Source

This module renders text graphs to visualize data on the terminal. A typical text graph looks like a bar graph as shown below:

  label1     3786 |----+----1----+----2---- ... ----+----7----+----8----+----9----+----|
  label2     3653 |----+----1----+----2---- ... ----+----7----+----8----+----9----+-
  label3     1055 |----+----1----+----2----+--
  label4      308 |----+---
  label5       70 |-
  label6      404 |----+----1
  label7       71 |-
  label8       32 |
 (each '-' is approximately 37.860 units.)

Sourceval render : ?narrow:bool -> (string * float) list -> string

Renders a text graph given labels and values. The list should be non-empty and the specified values must be positive numbers. Setting narrow enables narrower graphs.
