Sparklines are simple horizontal charts to give an indication of things, sometimes they are barcharts but we have nice smooth lines.
The only valid contents of the code-block is a single line of comma separated numbers.
The full set of optional arguments is
* title
* used as the generated images 'alt' argument
* bgcolor
* background color in hex (123456) or transparent
* line
* color or the line, in hex (abcdef)
* color
* area under the line, in hex (abcdef)
* scheme
* color scheme, only things in red blue green orange mono are valid
* size
* size of image, default 80x20, widthxheight
**Example**
## Gle / glx
This is a complex graph/chart drawing package available from http://glx.sourceforge.net/
The full set of optional arguments is
* title
* used as the generated images 'alt' argument
* size
* size of image, default 720x540, widthxheight, size is approximate
* transparent
* flag to use a transparent background
**Example**
