╭╴Extend Org Mode bar plots╶──╯
│ The standard Org Mode key-binding C-c " a
│ is extended with new Unicode styles of plots,
│ using Unicode block characters.
│ The new plots add visual vertical lines at selected coordinates
│ to better make sense of the graphic.
╰─────────────────────────────╮
╭╴Legacy usage╶───────────────╯
│ With out-of-the-box Org Mode, put the cursor in a column containing
│ numerical values, then type C-c " a
│ A new column is added with a bar plot.
│ When the table is refreshed (C-u C-c *),
│ the plot is updated to reflect the new values.
╰─────────────────────────────╮
╭╴New usage╶──────────────────╯
│ This package does not change:
│ - the key-binding: C-c " a
│ - the 3 legacy plots
│ This package changes:
│ - after C-c " a, asks for the type of plot (including legacy ones)
│ - gives the opportunity to change the min & max, and round them
╰─────────────────────────────╮
╭╴Zero dependencies╶──────────╯
│ As those plots are pure text, they do not require external
│ graphic formats (like JPG, GIF, PNG, SVG and so on).
│ The package itself is pure Emacs, it does not pull extra packages.
│ The only requirements are:
│ - to use a monospaced font able to display block characters.
│ - to encode the file in Unicode, for instance in UTF-8
