Template:Graph:Chart invokes function chartWrapper in Module:Graph using Lua.

CSV2Chart

If you have data from a spreadsheet document (e.g. LibreOffice Calc) or in a statistics software R/R-Studio, you can export them to CSV file. The CSV file can be loaded with an v:en:AppLSAC, that is able to convert the CSV in chart for the data. The column should have headers in the first row. The column of the CSV file contain float or integer values. CSV2WikiChart was created as support tool for Wikipedia and for Wikiversity learning resources that contain data.

Parameters

Examples

Basic examples

Scatter plot

By using a line plot with linewidth=0, it is possible to create a scatter plot: 

{{Graph:Chart
|width=500
|height=200
|type=line
|x=15.7,10.8,68.5,33.4,23.8,42.2,27.1,38.2,13.5,74.3
|y1=1517,970,4075,3819,2106,2919,2428,2164,1393,7603
|showSymbols=1
|linewidth=0
|yGrid= |xGrid= 
}}

Using percentages

  • When xAxisFormat or yAxisFormat is set to %, a percentage sign will be added to the scale of the corresponding axis.
  • A value of 1 equals 100%. A decimal point should be added in front of percentages between 0 and 100, for instance .25 for 25%.
  • Including the code | yAxisMin=0 | yAxisMax=1 will force the y axis scale to run from 0% to 100%.
{{Graph:Chart
| width = 450
| height = 350
| x = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23
| yAxisMin = 0
| yAxisMax = 1
| yAxisFormat = %
| showSymbols = 
| y1 = , , , .43, , , , .39, .43, .38, .38, .40, .48, .54 , .42, .47, .45, .48, .44, .41, .41, .45, .46
| y2 = .40, .377, .38, , .39, .38, .419, .55, .60, .63
| y3 = .27, .311, .31, , .26, .28, .285
| y4 = {{repeat|7|, }} .40, .44, .42, .47, .44, .43, .42
}}

A graph showing values greater than 100% and negative values: 

{{Graph:Chart
| width = 450
| height = 350
| x = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23
| yAxisFormat = %
| showSymbols = 
| y1 = 2, .43, 1.20, .39, .43, .0, -.38, -.20, .18, .54 , 0
}}

Legends

A legend can be added where there are multiple data series: 

{{Graph:Chart
 | width=400
 | height=150
 | xAxisTitle=X
 | yAxisTitle=Y
 | legend=Legend
 | y1Title=Blue
 | y2Title=Orange
 | type=line
 | x=1,2,3,4,5,6,7,8
 | y1=10,12,6,14,2,10,7,9
 | y2=2,4,6,8,13,11,9,2
}}

The title can be omitted by leaving the parameter blank: 

{{Graph:Chart
 | width=400
 | height=150
 | xAxisTitle=X
 | yAxisTitle=Y
 | legend=
 | y1Title=Blue
 | y2Title=Orange
 | type=line
 | x=1,2,3,4,5,6,7,8
 | y1=10,12,6,14,2,10,7,9
 | y2=2,4,6,8,13,11,9,2
}}

Long legend entries can look clumsy. It may be better to omit the legend parameter and use {{Legend}} (or a similar template) instead: 

{{Graph:Chart
 | width=400
 | height=150
 | xAxisTitle=X
 | yAxisTitle=Y
 | colors=darkred, gold
 | type=line
 | x=1,2,3,4,5,6,7,8
 | y1=10,12,6,14,2,10,7,9
 | y2=2,4,6,8,13,11,9,2
}}
{{legend|darkred|This is a long legend entry and wouldn't look so good if it was part of the graph itself.}}
{{legend|gold|This is another fairly long entry.}}
  This is a long legend entry and wouldn't look so good if it was part of the graph itself.
  This is another fairly long entry.


This method also allows the use of wiki formatting and the insertion of links. Graphs using the default colors need to specify the hex values in the legend templates: Template:Columns-list

Alternatively, CSS color names (or hex values) can be specified in the graph and the legend templates.

Annotations

Line Chart with horizontal annotations only: 

{{Graph:Chart
|hannotatonslabel=label4, label5, label6
|hannotatonsline=4, 5, 6
|linewidths=2,4,0
|showSymbols=3,3,3
|symbolsShape=triangle_up, cross, cross
|type=line
|x=0,1,2,3
|y1=0,3.342,2.3423,5.32423|y2=1,2.342,4.63,2.32423|y3=3,1.342,2.63,6.32423}}

Area chart with vertical annotations only 

{{Graph:Chart
|vAnnotatonsLine=1, 2, 3 
|vAnnotatonsLabel=label1, label2, label3
|colors=#ffff5ba0, #641050ff, #ffaaff00
|type=area
|x=0,1,2,3
|y3=0,3.342,2.3423,5.32423|y2=1,2.342,4.63,2.32423|y1=3,1.342,2.63,6.32423}}

Display

Putting a Chart in an {{image frame}} allows the graph to float and text may wrap around it:

{{Image frame 
 | caption=Line chart 
 | content = {{Graph:Chart
   | width=400
   | height=150
   | type=line
   | yAxisMin = -1
   | x=1,2,3,4,5,6,7,8|y=10,12,6,14,2,10,7,9
  }} 
}}
