Example: Filling the data

final ChartModel model = ChartModel.New()
    .addColumn(Column.New(Type.STRING, "caption", "Caption"))
    .addColumn(Column.New(Type.NUMBER, "min value", "Lunte"))
    .addColumn(Column.New(Type.NUMBER, "max value", "Docht"))
    .addColumn(Column.New(Type.NUMBER, "open value", "Eröffnung"))
    .addColumn(Column.New(Type.NUMBER, "close value", "Schluss"));

model.addRow("Mon", 5, 10, 7, 8);
model.addRow("Tue", 5, 10, 8, 7);
model.addRow("Wen", 6, 12, 7, 11);
model.addRow("Thu", 7, 13, 11, 9);
model.addRow("Fri", 7, 13, 9, 13);

this.candlestickChart.setModel(model);

Properties

Orientation

The orientation of the chart. With the setting 'vertical' the axes of the chart are rotated, so that (for example) a column chart becomes a bar chart and an area chart grows to the right instead of upwards:

candlestick.setOrientation(Orientation.VERTICAL);
