[[template id=plugin name=postsparkline author="[[Joey]]"]] [[tag type/chrome]]

This plugin uses the [[sparkline]] plugin to create a sparkline of statistics about a set of pages, such as posts to a blog.

examples

Post interval: 
\[[postsparkline pages="blog/* and !*/Discussion" max=100
formula=interval style=bar barwidth=2 barspacing=1 height=13]]

Posts per month this year: 
\[[postsparkline pages="blog/* and !*/Discussion" max=12
formula=permonth style=bar barwidth=2 barspacing=1 height=13]]

usage

All options aside fron the pages, max, and forumla options are passed on to the sparkline plugin.

You don't need to specify any data points (though you can if you want to). Instead, data points are automatically generated based on the creation times of pages matched by the specified pages [[PageSpec]]. A maximum of max data points will be generated.

The formula parameter controls the formula used to generate data points. Available forumlae:

  • interval - The height of each point represents how long it has been since the previous post.
  • perday - Each point represents a day; the height represents how many posts were made that day.
  • permonth - Each point represents a month; the height represents how many posts were made that month.
  • peryear - Each point represents a day; the height represents how many posts were made that year.

adding formulae

Additional formulae can be added without modifying this plugin by writing plugins that register functions in the IkiWiki::Plugin::postsparkline::formula namespace. These functions will receive on input a reference to a hash of parameters, and a sorted list of pages (newest pages first), and should return a list of data points for the sparkline plugin.
