Resize Chart's Data Label Shape To Fit Text

Excel application provides the Resize shape to fit text option for Chart’s DataLabels in order to increase the size of the shape so that the text fits inside of it. This option can be accessed on Excel interface by selecting any of the data labels on the chart. Right click and select Format DataLabels menu. On Size & Properties tab, expand Alignment to reveal the related properties including the Resize shape to fix text option.

Resize Chart’s Data Label Shape To Fit Text

In order to mimic Excel’s feature of resizing data label shapes to fit the text, the Aspose.Cells APIs have exposed the Boolean type DataLabels.ResizeShapeToFitText property. The following piece of code shows the simple usage scenario of DataLabels.ResizeShapeToFitText property.

The chart looks as follows before executing the code.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(ResizeChartDataLabelShapeToFitText.class);
// Create an instance of Workbook containing the Chart
Workbook book = new Workbook(dataDir + "report.xlsx");

// Access the Worksheet that contains the Chart
Worksheet sheet = book.getWorksheets().get(0);

// Access ChartCollection from Worksheet
ChartCollection charts = sheet.getCharts();

// Loop over each chart in collection
for (int chartIndex = 0; chartIndex < charts.getCount(); chartIndex++) {
	// Access indexed chart from the collection
	Chart chart = charts.get(chartIndex);

	for (int seriesIndex = 0; seriesIndex < chart.getNSeries().getCount(); seriesIndex++) {
		// Access the DataLabels of indexed NSeries
		DataLabels labels = chart.getNSeries().get(seriesIndex).getDataLabels();

		// Set ResizeShapeToFitText property to true
		labels.setResizeShapeToFitText(true);
	}

	// Calculate Chart
	chart.calculate();
}

// Save the result
book.save(dataDir + "output.xlsx");
