Examples

Shows how to set formatting for chart values.

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

Shape shape = builder.InsertChart(ChartType.Column, 500, 300);
Chart chart = shape.Chart;

// Clear the chart's demo data series to start with a clean chart.
chart.Series.Clear();

// Add a custom series to the chart with categories for the X-axis,
// and large respective numeric values for the Y-axis. 
chart.Series.Add("Aspose Test Series",
    new[] { "Word", "PDF", "Excel", "GoogleDocs", "Note" },
    new double[] { 1900000, 850000, 2100000, 600000, 1500000 });

// Set the number format of the Y-axis tick labels to not group digits with commas. 
chart.AxisY.NumberFormat.FormatCode = "#,##0";

// This flag can override the above value and draw the number format from the source cell.
Assert.False(chart.AxisY.NumberFormat.IsLinkedToSource);

Shows how to enable and configure data labels for a chart series.

Chart chart = shape.Chart;
chart.Series.Clear();
chart.Title.Text = "Monthly sales report";

// Insert a custom chart series with months as categories for the X-axis,
// and respective decimal amounts for the Y-axis.
ChartSeries series = chart.Series.Add("Revenue",
    new[] { "January", "February", "March" },
    new[] { 25.611d, 21.439d, 33.750d });

// Enable data labels, and then apply a custom number format for values displayed in the data labels.
// This format will treat displayed decimal values as millions of US Dollars.
series.HasDataLabels = true;
ChartDataLabelCollection dataLabels = series.DataLabels;
dataLabels.ShowValue = true;
dataLabels.NumberFormat.FormatCode = "\"US$\" #,##0.000\"M\"";
