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, andrect
for (column) bar charts, andpie
for pie charts. Multiple series can stacked using thestacked
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
theaa
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), andstring
for ordinal values (usestring
to prevent axis values from being repeated when there are only a few values). - 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
