Example 1 with LegendProperties

use of org.krysalis.jcharts.properties.LegendProperties in project activityinfo by bedatadriven.

the class ChartRendererJC method computeLegendProperties.

protected LegendProperties computeLegendProperties(PivotChartReportElement element, int dpi, List<PivotTableData.Axis> series) {
    // if there is only series, there is no need for a legend
    if (series.size() <= 1) {
        return null;
    }
    ChartFont font = new ChartFont(new Font(SANS_SERIF, Font.PLAIN, fontSize(10, dpi)), Color.BLACK);
    LegendProperties p = new LegendProperties();
    p.setChartFont(font);
    p.setBorderStroke(null);
    p.setIconBorderPaint(null);
    if (element.getType() == Type.Pie) {
        p.setPlacement(LegendProperties.RIGHT);
    } else {
        p.setPlacement(maxLegendTextLength(series) > 30 ? LegendProperties.BOTTOM : LegendProperties.RIGHT);
    }
    p.setNumColumns(1);
    return p;
}
