Examples

Shows how to work with data points on a line chart.

{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    Shape shape = builder.InsertChart(ChartType.Line, 500, 350);

    Assert.That(chart.Series.Count, Is.EqualTo(3));
    Assert.That(chart.Series[0].Name, Is.EqualTo("Series 1"));
    Assert.That(chart.Series[1].Name, Is.EqualTo("Series 2"));
    Assert.That(chart.Series[2].Name, Is.EqualTo("Series 3"));

    // Emphasize the chart's data points by making them appear as diamond shapes.
    foreach (ChartSeries series in chart.Series)
        ApplyDataPoints(series, 4, MarkerSymbol.Diamond, 15);

    // Smooth out the line that represents the first data series.
    chart.Series[0].Smooth = true;

    // Verify that data points for the first series will not invert their colors if the value is negative.
    using (IEnumerator<ChartDataPoint> enumerator = chart.Series[0].DataPoints.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            Assert.That(enumerator.Current.InvertIfNegative, Is.False);
        }
    }

    ChartDataPoint dataPoint = chart.Series[1].DataPoints[2];
    dataPoint.Format.Fill.Color = Color.Red;

    // For a cleaner looking graph, we can clear format individually.
    dataPoint.ClearFormat();

    // We can also strip an entire series of data points at once.
    chart.Series[2].DataPoints.ClearFormat();

    doc.Save(ArtifactsDir + "Charts.ChartDataPoint.docx");
