Sjabloon:GraphChart
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. - 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.
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.
Examples
Line Chart:
{{GraphChart|width=400|height=100|type=line|x=1,2,3,4,5,6,7,8|y=10, 12, 6, 14, 2, 10, 7, 9}}
Note: The y-axis starts from the smallest y value, though this can be overridden with the yAxisMin parameter.
Area chart:
{{GraphChart|width=400|height=100|type=area|x=1,2,3,4,5,6,7,8|y=10, 12, 6, 14, 2, 10, 7, 9}}
Note: The y-axis starts from zero
Bar chart:
{{GraphChart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y|type=rect|x=1,2,3,4,5,6,7,8|y=10, 12, 6, 14, 2, 10, 7, 9}}
Line chart with more than one data series, using colors:
{{GraphChart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y|legend=Legend|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|colors=#0000aa,#ff8000}}
Area chart with more than one data series showing blended overlap:
