Markup:

• <value> indicates value is a variable to be substituted.
• [/name/<value>] indicates name is an optional parameter.

Lijst.com currently lets you adjust the date interval and image size.

Date Interval

A chart can be limited to a time window. This interval can be set using the number of days to show.

The end of the interval is set to the moment of the request (now).

Not Implemented [/<end date>]

Format: YYYYMMDD

The inclusive end date of the interval to chart. When not submitted, this value defaults to today.

Examples

/20100101

Chart will contain data up to and on the first of Jan 2010.

/20091231

Chart will contain data up to the first of Jan 2010.

[/days/<number>]

The number of days to show.

For now, a negative number of days is allowed. negative days might become invalid in the future. Using a negative number of days enables you to show a chart of upcoming data.

Examples

/days/30

Show the last 30 days, equivalent to the default

/days/1

Show the chart for all today's values

Combined examples

/20081231/days/31

Chart data in December 2008

/20081231/days/365

Chart all of 2008

Image Size

Not Implemented /size/[width]x[height]

• Width/height ratio defaults to 4/3. The same ratio as 640x480 pixels (old skool VGA).

Examples

/size/160x160

Set chart image size to a squared of 160 by 160 pixels.

/size/640x

Set width to 640 pixels. Height will follow the default width/height ratio of 4/3: 480 pixels

/size/x180

Set height to 180 pixels. Width will be relative: 240 pixels.
