读取和操作 Excel 2016 图表

可能的使用场景

Aspose.Cells 支持读取和操作 Microsoft Excel 2016 图表，这些图表在 Microsoft Excel 2013 或更早版本中不存在。

读取和操作 Excel 2016 图表

下面的示例代码加载源文件其中包含第一个工作表中的 Microsoft Excel 2016 图表。它会一张一张地读取所有图表，并根据图表类型更改其标题。以下屏幕截图显示了代码执行前的源 excel 文件。如您所见，所有图表的图表标题都相同。

以下屏幕截图显示了输出excel文件代码执行后。如您所见，图表标题根据其图表类型进行了更改。

示例代码

// 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.getSharedDataDir(ReadManipulateExcel2016Charts.class) + "charts/";

// Load source excel file containing excel 2016 charts
Workbook wb = new Workbook(dataDir + "excel2016Charts.xlsx");

// Access the first worksheet which contains the charts
Worksheet ws = wb.getWorksheets().get(0);

//Converting integer enums to string enums
HashMap<Integer, String> cTypes = new HashMap<Integer, String>();
cTypes.put(ChartType.BOX_WHISKER, "BoxWhisker");
cTypes.put(ChartType.WATERFALL, "Waterfall");
cTypes.put(ChartType.TREEMAP, "Treemap");
cTypes.put(ChartType.HISTOGRAM, "Histogram");
cTypes.put(ChartType.SUNBURST, "Sunburst");

// Access all charts one by one and read their types
for (int i = 0; i < ws.getCharts().getCount(); i++) {
	// Access the chart
	Chart ch = ws.getCharts().get(i);

	// Print chart type
	String strChartType = cTypes.get(ch.getType());
	System.out.println(strChartType);

	// Change the title of the charts as per their types
	ch.getTitle().setText("Chart Type is " + strChartType);
}

// Save the workbook
wb.save(dataDir + "out_excel2016Charts.xlsx");

// Print message
System.out.println("Excel 2016 Chart Titles changed successfully.");
