[[Help:Result formats/zh-hans|结果格式]]'''jqplotchart'''（jqPlot图表），displays aggregated numerical data as a bar, line, pie, or donut chart. 

It is using the jqPlot Javascript library and starting with SRF 1.8, jqplotbar and jqplotpie have been merged into one class called jqplotchart which will handle all standard tasks that earlier jqplotbar and jqplotpie have managed. For compatibility reasons the format name jqplotbar and jqplotpie will still be available as aliases but point to format '''jqplotchart''' where the bar chart is set as default chart. Other chart layouts are available by using parameter ['layout'] which introduces two additional layouts, a line and a donut chart layout.

The change tried to accommodate compatibility as best as possible but some parameters have been either renamed or altered in their usage pattern to ensure similar behaviour across all layouts and in both classes ( jqplotchart and '''[[Help:Jqplotseries format|jqplotseries]]''').

=== 参数值 ===
As [[Thread:Help talk:Eventcalendar format/Parameter values|a list of values cannot be listed yet]] (see also [[Thread:Help talk:Jqplotchart format/Parameter descriptions|here]]), here are some options what parameter values can be chosen, e.g. <code>direction=horizontal</code>.
*direction: vertical, horizontal
*charttype: bar, donut, line, pie
*datalabels: none, value, label, percent

=== Changes deployed with SRF 1.8===
* Added donut and line chart layout
* Added parameter [class], allows to add CSS characteristics 
* Added parameter [charttext], a text field for an explanatory chart text
* Added parameter [smoothlines], applies a smoothing algorithm (only applied to the line chart) 
* Added parameter [theme], a basic theming support for commonly styled attributes (vector, simple)
* Added parameter [colorscheme], option for an easy selection of pre-defined colours schemes
* Added parameter [datalabels], displays individual data as ( 'none', 'value', 'label', 'percent')
* Changed parameter [bardirection] to [direction] to accommodate overall changes

=== 值分布 ===
The value distribution is supported as well with '''jqplotchart'''  as it was with jqplotbar and jqplotpie.

== 备注 ==
Reasons for the re-factoring effort was to ensure that the jqplot printer and its JavaScript plug-ins are used entirely  throughout the ResourceLoader, eliminate identical code among jqplotbar and jqplotpie classes, and make use of the same JavaScript for both '''jqplotseries''' and '''jqplotchart''' class.
