- 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

-# usage
-
-All options aside fron the `pages`, `max`, `formula`, `time`, and `color`
-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` [[ikiwiki/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.
-
-The `time` parameter has a default value of "ctime", since forumae use
-the creation times of pages by default. If you instead want
-them to use the modification times of pages, set it to "mtime".
-
-To change the color used to draw the sparkline, use the `color` parameter.
-For example, "color=red".
