Using the Chart class

The Chart class is the proxy for the ColdFusion Chart service, which provides the functionality of the cfchart tag and its child chartdata and chartseries tags.

  • You specify the cfchart attributes as Chart object properties.

  • You represent chart series in the chartSeries element of the chart object. The chartSeries element is an arrays of objects, each of which represents a single chart (chartseries tag) document section. These objects include a type element for the chart type, a chartdata element for the chart data, and elements for any other series attributes.

  • You represent each chart's data as an array of objects, each of which contains an item element and a value element. You use these arrays as the chartdata elements of the chartSeries object.

  • You call the document object execute() function to run the service.

The following example shows how you can use the chart service:
