Template:Chart/doc

This is a template for rendering simple diagrams consisting of boxes and connecting lines based loosely on an ASCII art-like syntax. The trees are displayed as HTML tables using CSS attributes, and may contain arbitrary wiki markup within the boxes. This implementation was based on the familytree template.

Example usage
This code:

Parameters
This template produces one row in a family tree table. The template accepts up to 50 unnamed parameters describing the contents of the table. Each parameter specifies a tile or a box.


 * Tiles are line drawing symbols consisting of horizontal and vertical lines and various corners and crossings thereof. Tiles are specified using one- or two-character symbols: for the most common tiles, that character is more or less approximate the shape of the tile in appearance. A special case of a tile is the empty tile, specified by a single space character. A table of available tiles is given below.


 * Boxes can contain arbitrary wiki markup. The content of each box is specified using additional named parameters appended to the template call. Each box is three tiles wide and normally has a black border two pixels wide. Boxes can have any name that is a valid template parameter name, subject to a minimum of two alphabetical characters.

Style attributes
The appearance of the boxes may be controlled by the following optional template parameters: For example, the following code:
 * border specifies the width of the box border in pixels,
 * boxstyle can be used to append arbitrary CSS declarations directly to the box style attributes.

produces this chart:

Style attributes can even be set for individual boxes, as in the example below:

which produces this:

NOTE: When specifying style attributes for individual named boxes, make sure the box names are aligned to the left side of the area reserved for them in the template call (as in " " instead of " " in the example above), otherwise the template will end up looking for a style parameter with spaces in its name.

The chart/start template also accepts an optional style parameter that can be used to set CSS styles for the entire diagram.

Migration from familytree
The chart template is largely compatible with the earlier familytree template. However, to use the additional functionality offered with this template, diagrams must be updated to use chart instead. Many familytree diagrams can be altered to use chart and its sub-templates simply by replacing the wikitext familytree with chart. A few of the "mixed" tiles had to be renamed, and familytree diagrams using these tiles will have to make a few changes. Additionally, two new "mixed" tiles have been added, joining solid lines to dashed lines. The following table summarises the differences:

Lastly, if any uses of the familytree template end with |}}, that vertical bar should be removed, leaving the last cell in that row containing either some text or a space.

The familytree.js tool below can be used to convert between syntaxes. Just change the start tag when in edit view, then click "Art → Templates" to toggle back to wikitext view. The other templates will be updated to match.
