This module is rated as alpha. It is ready for third party input, and may be used on a few pages to see if problems arise, but should be watched. Suggestions for new features or changes in their input and output mechanisms are welcome.

Module with helper functions for the Graph extension. From de:Modul:Graph.

Functions for templates

`chart`

Creates a JSON object for <graph> to display charts. In the article namespace the template Template:Graph:Chart should be used instead. See its page for use cases.

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/vega/vega/wiki/Marks#area.
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: ).
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 and https://github.com/d3/d3-3.x-api-reference/blob/master/Time-Formatting.md for date/time. For example, the format % can be used to output percentages.
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).
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.
x: the x-values as a comma-separated list
y or y1, y2, …: the y-values for one or several data series, respectively. For pie charts y2 denotes the radiuses of the corresponding sectors.
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.
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:
- 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.
showSymbols: For line charts: show a symbol (circle) at each data point. (usage: showSymbols=true)
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.
formatjson: format JSON object for better legibility

Template wrappers

The functions mapWrapper and chartWrapper are wrappers to pass all parameters of the calling template to the respective map and chart functions.

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. {{#invoke:Graph
