Class ChartDataPoint

java.lang.Object
    extended by com.aspose.words.ChartDataPoint
All Implemented Interfaces:
IChartDataPoint, java.lang.Cloneable

public class ChartDataPoint 
extends java.lang.Object

Allows to specify formatting of a single data point on the chart. On a series, the ChartDataPoint object is a member of the ChartDataPointCollection. The ChartDataPointCollection contains a ChartDataPoint object for each point.

Example:

Shows how to customize chart data points.
@Test
public void chartDataPoint() throws Exception {
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Add a line chart, which will have default data that we will use
    Shape shape = builder.insertChart(ChartType.LINE, 500.0, 350.0);
    Chart chart = shape.getChart();

    // Apply diamond-shaped data points to the line of the first series
    for (ChartSeries series : chart.getSeries()) {
        applyDataPoints(series, 4, MarkerSymbol.DIAMOND, 15);
    }

    // We can further decorate a series line by smoothing it
    chart.getSeries().get(0).setSmooth(true);

    // Get the enumerator for the data point collection from one series
    Iterator<ChartDataPoint> enumerator = chart.getSeries().get(0).getDataPoints().iterator();

    // And use it to go over all the data labels in one series and change their separator
    while (enumerator.hasNext()) {
        Assert.assertFalse(enumerator.next().getInvertIfNegative());
    }

    // If the chart looks too busy, we can remove data points one by one
    chart.getSeries().get(1).getDataPoints().removeAt(2);

    // We can also clear an entire data point collection for one whole series
    chart.getSeries().get(2).getDataPoints().clear();
