Class ezcGraphPieChart
Class for pie charts. Can only use one dataset which will be dispalyed as a pie chart.
- // Create a new pie chart
- // Add data to line chart
- array(
- 'one' => 1.2,
- 'two' => 43.2,
- 'three' => -34.14,
- 'four' => 65,
- 'five' => 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 pie chart consists of:
- title ( ezcGraphChartElementText )
- legend ( ezcGraphChartElementLegend )
- background ( ezcGraphChartElementBackground )
The chart itself also offers several options to configure the appearance. The extended configure options are available in ezcGraphPieChartOptions extending the ezcGraphChartOptions.
