MediaWiki User Guide/Graphs

MediaWiki has graph extension that allows to enter data into the wiki markup and have a graph rendered automatically as a raster image. Many wikis have Graph:Chart template that encapsulates the raw markup for the graphs.

A mimimal example of a line chart:

{{Graph:Chart|x=1,2,3,4,5|y=5,4,3,2,1}}

A bar chart with dimensions, axis titles, a grid that shows values above the bars and setting of a bar color:

{{Graph:Chart
 |width=700|height=150
 |xAxisTitle=Axis X|yAxisTitle=Axis Y
 |type=rect
 |xGrid=
 |yGrid=
 |colors=#66CC66
 |showValues=offset:2
 |x=1,2,3,4,5|y=5,4,3,2,1}}

A line chart with x-axis values of the type date and x-axis labels at an angle:

{{Graph:Chart
 |type=line
 |xType=date
 |xAxisFormat=%b %e
 |xAxisAngle=-45
 |x=2020/01/05,2020/01/01,2020/01/02,2020/01/03,2020/01/04|y=1,5,4,3,2}}

A line chart with two data series with line colors set and a legend:

 |x=1,2,3,4,5
 |y1=1,4,9,16,25
 |y2=1,8,27,64,125
}}

A semilog line chart, that is, one with logarithmic scale of the y-axis:

{{Graph:Chart
 |type=line
 |yScaleType=log
 |x=1, 2, 3, 4, 5, 6, 7, 8, 9, 10
 |y=3, 7, 20, 55, 148, 403, 1097, 2981, 8103, 22026
