Example 1 with IChartField

use of org.eclipse.linuxtools.dataviewers.charts.provider.IChartField in project linuxtools by eclipse.

the class ChartDialog method produceChart.

/**
 * Build the chart from configuration
 *
 * @return a new chart
 */
private Chart produceChart() {
    IStructuredSelection selection = (IStructuredSelection) stViewer.getViewer().getSelection();
    if (selection == StructuredSelection.EMPTY)
        return null;
    Object[] objects = selection.toArray();
    ISTDataViewersField labelField = getLabelField(stViewer);
    List<IChartField> selectedFields = new ArrayList<>();
    for (Button button : columnButtons) {
        if (button.getSelection()) {
            selectedFields.add((IChartField) button.getData());
        }
    }
    boolean barChartType = barGraphButton.getSelection();
    boolean horizontalBars = !verticalBarsButton.getSelection();
    if (barChartType) {
        return ChartFactory.produceBarChart(objects, labelField, selectedFields, Messages.ChartConstants_BAR_GRAPH, horizontalBars);
    } else {
        return ChartFactory.producePieChart(objects, labelField, selectedFields, Messages.ChartConstants_PIE_CHART);
    }
}
