Sjabloon:GraphChart

De sjabloonbeschrijving hieronder wordt niet afgebeeld wanneer het sjabloon wordt geplaatst

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.
• 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).
• 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:
{{GraphChart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y|legend=Legend|type=area|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=#800000aa,#80ff8000}}

Bar chart with multiple data series:
{{GraphChart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y|legend=Legend|type=area|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=#800000aa,#80ff8000}}

Area chart with smoothed data values:
{{GraphChart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y|legend=Legend|type=stackedarea|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|interpolate=monotone|colors=seagreen, orchid}}

Bar chart with stacked data series:
{{GraphChart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y|legend=Legend|type=stackedrect|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|y1Title=Data A|y2Title=Data B|colors=seagreen, orchid}}
