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
Axis:
- Numeric axis
- radar axis label renderer
1. // Create a new radar chart
2. $chart = new ezcGraphRadarChart();
3.
4. // Add data to line chart
5. $chart->data['sample dataset'] = new ezcGraphArrayDataSet(
6. array(
7. '100' => 1.2,
8. '200' => 43.2,
9. '300' => -34.14,
10. '350' => 65,
11. '400' => 123,
12. )
13. );
14.
15. // Render chart with default 2d renderer and default SVG driver
16. $chart->render( 500, 200, 'radar_chart.svg' );
Each chart consists of several chart elements which represents logical parts of the chart and can be formatted independently. The line chart consists of:
The type of the axis may be changed and all elements can be configured by accessing them as properties of the chart:
1. $chart->legend->position = ezcGraph::RIGHT;
