Class ezcGraphRadarChart
Class for radar charts.
Can make use of an unlimited amount of datasets and will display them as lines by default. Rotation axis:
- Labeled axis
- Centered axis label renderer
- Numeric axis
- radar axis label renderer
- // Create a new radar chart
- // Add data to line chart
- array(
- '100' => 1.2,
- '200' => 43.2,
- '300' => -34.14,
- '350' => 65,
- '400' => 123,
- )
- );
- // Render chart with default 2d renderer and default SVG driver
Each chart consists of several chart elements which represents logical parts of the chart and can be formatted independently. The line chart consists of:
- title ( ezcGraphChartElementText )
- legend ( ezcGraphChartElementLegend )
- background ( ezcGraphChartElementBackground )
- axis ( ezcGraphChartElementNumericAxis )
- ratation axis ( ezcGraphChartElementLabeledAxis )
The chart itself also offers several options to configure the appearance. The extended configure options are available in ezcGraphRadarChartOptions extending the ezcGraphChartOptions.
