charts

Provides integration with JFreeChart by means of ChartBuilder.

Usage

The following nodes will become available on a View script upon installing this plugin

If a Class is set as the value for chart: then it is assumed to be a script that can be parsed using ChartBuilder

Scripts

• create-chart - creates a new Chart script that can be parsed using ChartBuilder

Example

Chart scripts have access to all variables form their surrounding context. This means that a chart can read properties from a Model if the chart is built inside a View script. Here is how the typical chart Script looks like

griffon-app/conf/charts/sample/SampleChart.groovy

    package sample
    import java.awt.Color
    import java.awt.Font
    import org.jfree.chart.labels.PieToolTipGenerator

    def largeFont = new Font('Arial', Font.BOLD, 15)

    piechart3d(title: 'Simple Pie Chart') {
        defaultPieDataset {
            Series1(40.0f)
            Series2(30.0f)
            Series3(30.0f)
        }
        antiAlias = true
        backgroundPaint(Color.WHITE)

        pieplot {
            sectionOutlinesVisible false
            labelFont largeFont
            labelGap 0.02
            toolTipGenerator ({ dataset, key -> return "[${dataset} ${key}]" as String } as PieToolTipGenerator)

            sectionPaint('Series1', paint: new Color(255,0,0))
            sectionPaint('Series2', paint: new Color(0,255,0))
            sectionPaint('Series3', paint: new Color(0,0,255))
        }
    }

This is how the previously defined chart may be embedded in a View

griffon-app/views/sample/SampleView.groovy

    package sample
    application(title: 'Charts',
            preferredSize: [320, 240],
            pack: true,
            locationByPlatform:true,
            iconImage: imageIcon('/griffon-icon-48x48.png').image,
            iconImages: [imageIcon('/griffon-icon-48x48.png').image,
            imageIcon('/griffon-icon-32x32.png').image,
            imageIcon('/griffon-icon-16x16.png').image]) {
        chart(SampleChart)
    }
