class (none) \ GraphRenderer_ExternalHistorical

This line graph renderer abstracts away common functionality for graphs that - get data from the database - from a number of sources, which have to be collated together - returns data based on dates - returns 1..2 values (from GraphRenderer_AbstractTicker)

Method Summary

Name	Description
__construct($job_type = false, $arg0 = false)
getLabel()	Get the label that should be associated with the #getURL(), or `false` if there shouldn't be any. Should be wrapped in ct().
getTickerArgs()
getTickerColumns()
getTickerData($row)
getTickerSources($days, $extra_days)	The sources must return 'created_at' column as well, for last_updated
getTitle()	Get the title of this graph
getURL()	Get the URL that the title of this graph should link to, or `false` if it should not link anywhere

Inherited Method Summary

Name	Description
canHaveTechnicals()	Can this graph have technicals? If this returns `true`, then the resulting data will always be sorted. By default, returns `true`. (from GraphRenderer)
convertGraphToProportional($original)	Relabel all columns to have ' %' prefix, and reformat all data to be proportional based on the sum of each row. Uses the output of #getData(). (from GraphRenderer)
getChartType()	What type of chart is this rendered as? By default, returns `linechart`. (from GraphRenderer)
getClasses()	(from GraphRenderer)
getCustomSubheading()	Calculate the custom subheading value for this graph, or `false` if this graph does not have a custom subheading defined (and subheadings calculated through #hasSubheading() will use default sum/array logic). By default, returns `false`. (from GraphRenderer)
getData($days)	(from GraphRenderer_AbstractTicker)
getTitleArgs()	Get any localisation (i18n) string arguments for the title given in #getTitle(). By default, returns an empty array. (from GraphRenderer)
getUser()	(from GraphRenderer)
hasSubheading()	Does this graph have a subheading? By default, returns `true`. (from GraphRenderer)
requiresAdmin()	Does rendering this graph require an admin user? By default, returns `false`. (from GraphRenderer)
requiresUser()	Does rendering this graph require a user? By default, returns `false`. (from GraphRenderer)
setUser($user_id)	(from GraphRenderer)
usesDays()	Does this function require a days parameter? If `true`, then the returned data will be stripped based on the keys returned in the data - assumes that the data uses dates as keys. By default, returns `true`. (from GraphRenderer)
usesSummaries()	Does this graph use summaries which may be out of date for a user? By default, returns `false`. (from GraphRenderer)
isDaily()	(from GraphRenderer_AbstractTicker)
