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. Due to temporary disable graphs an added feature of CSV2WikiChart allows SVG export of charts.

Parameters

• width: width of the chart
• height: height of the chart
• type: type of the chart: line for line charts, area for area charts, and rect for (column) bar charts, and pie for pie charts. Multiple series can stacked using the stacked prefix, e.g. stackedarea.
• interpolate: interpolation method for line and area charts. It is recommended to use monotone for a monotone cubic interpolation – further supported values are listed at https://github.com/nyurik/vega/wiki/Marks#line.
• colors: color palette of the chart as a comma-separated list of colors. The color values must be given either as #rgb/#rrggbb/#aarrggbb or by a CSS color name. For #aarrggbb the aa component denotes the alpha channel, i.e. FF=100% opacity, 80=50% opacity/transparency, etc. (The default color palette if n <= 10 is Category10:                                         else is Category20:                                                                                ). See Template:ChartColors for details.
• xAxisTitle and yAxisTitle: captions of the x and y axes
• xAxisMin, xAxisMax, yAxisMin, and yAxisMax: minimum and maximum values of the x and y axes (not yet supported for bar charts). These parameters can be used to invert the scale of a numeric axis by setting the lowest value to the Max and highest value to the Min.
• xAxisFormat and yAxisFormat: changes the formatting of the axis labels. Supported values are listed at https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#numbers for numbers. For example, the format % can be used to output percentages. For date/time specification of supported values is https://github.com/d3/d3-3.x-api-reference/blob/master/Time-Formatting.md , e.g. xAxisFormat=%d-%m-%Y for result 13-01-1977.
• xAxisAngle: rotates the x axis labels by the specified angle. Recommended values are: -45, +45, -90, +90
• xType and yType: data types of the values, e.g. integer for integers, number for real numbers, date for dates (e.g. YYYY-MM-DD), and string for ordinal values (use string to prevent axis values from being repeated when there are only a few values). Remarks: Date type doesn't work for bar graphs. For date data input please use ISO date format (e.g. YYYY-MM-DD) acc. to date and time formats used in HTML. Other date formats may work but not in all browsers. Date is unfortunately displayed only in en-US format for all Wikipedia languages. Workaround is to use xAxisFormat and yAxisFormat with numerical dates format.
• xScaleType and yScaleType: scale types of the x and y axes, e.g. linear for linear scale (default), log for logarithmic scale and sqrt for square root scale.

  A logarithmic chart allows only positive values to be plotted. A square root scale chart cannot show negative values.

• x: the x-values as a comma-separated list, for dates and time see remark in xType and yType
• yory1, y2, …: the y-values for one or several data series, respectively. For pie charts y2 denotes the radius of the corresponding sectors. For dates and time see remark in xType and yType
• legend: show legend (only works in case of multiple data series)
• y1Title, y2Title, …: defines the label of the respective data series in the legend
• linewidth: line width for line charts or distance between the pie segments for pie charts. Setting to 0 with type=line creates a scatter plot.
• linewidths: different line widths may be defined for each series of data with csv, if set to 0 with "showSymbols" results with points graph, eg.: linewidths=1, 0, 5, 0.2
• showSymbols: show symbol on data point for line graphs, if a number is provided, the symbol size (default 2.5) may be defined for each data series, eg.: showSymbols=1, 2, 3, 4
• symbolsShape: custom shape for symbol: circle, x, square, cross, diamond, triangle_up, triangle_down, triangle_right, triangle_left. May be defined for each series of data with csv, eg.: symbolsShape= circle, cross, square
• symbolsNoFill: if true symbol will be without fill (only stroke),
• symbolsStroke: if "x" symbol is used or option "symbolsNoFill" symbol stroke width, default 2.5
• showValues: Additionally, output the y values as text. (Currently, only (non-stacked) bar and pie charts are supported.) The output can be configured used the following parameters provided as name1:value1, name2:value2 (e.g. |showValues=fontcolor:blue,angle:0).
  • format: Format the output according to https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#numbers for numbers and https://github.com/d3/d3-3.x-api-reference/blob/master/Time-Formatting.md for date/time.
  • fontcolor: text color
  • fontsize: text size
  • offset: move text by the given offset. For bar charts and pie charts with midangle this also defines if the text is inside or outside the chart.
  • angle (pie charts only): text angle in degrees or midangle (default) for dynamic angles based on the mid-angle of the pie sector.
• innerRadius: For pie charts: defines the inner radius to create a doughnut chart.
• xGrid and yGrid: display grid lines on the x and y axes.
• Annotations
  • vAnnotatonsLine and hAnnotatonsLine: display vertical or horizontal annotation lines on specific values e.g. hAnnotatonsLine=4, 5, 6
  • vAnnotatonsLabel and hAnnotatonsLabel: display vertical or horizontal annotation labels for lines e.g. hAnnotatonsLabel = label1, label2, label3

Note: In the editor preview the graph extension creates a canvas element with vector graphics. However, when saving the page a PNG raster graphics is generated instead.

|showSymbols=1|linewidth=0
|yGrid= |xGrid= 
}}

Using percentages

• When xAxisFormatoryAxisFormat 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

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
}}

Graphs are unavailable due to technical issues. There is more info on Phabricator and on MediaWiki.org.

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
}}

Graphs are unavailable due to technical issues. There is more info on Phabricator and on MediaWiki.org.

Long legend entries can look clumsy. It may be better to omit the legend parameter and use {{Legend}} (ora 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.}}

Graphs are unavailable due to technical issues. There is more info on Phabricator and on MediaWiki.org.

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:

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}}

Graphs are unavailable due to technical issues. There is more info on Phabricator and on MediaWiki.org.

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}}

Graphs are unavailable due to technical issues. There is more info on Phabricator and on MediaWiki.org.

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
  }} 
}}

Graphs are unavailable due to technical issues. There is more info on Phabricator and on MediaWiki.org.

To add a title above the chart and source links below the chart, an option is to use |pos=topin{{image frame}}.
