Sample Code

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

Aspose::Cells::Startup();

//Source directory path
U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

//Output directory path
U16String outDir(u"..\\Data\\02_OutputDirectory\\");

//Path of input excel file
U16String sampleReadAndManipulateExcel2016Charts = srcDir + u"sampleReadAndManipulateExcel2016Charts.xlsx";

//Path of output excel file
U16String outputReadAndManipulateExcel2016Charts = outDir + u"outputReadAndManipulateExcel2016Charts.xlsx";

// Load sample Excel file containing Excel 2016 charts
Workbook workbook(sampleReadAndManipulateExcel2016Charts);

// Access the first worksheet which contains the charts
Worksheet worksheet = workbook.GetWorksheets().Get(0);

// Access all charts one by one and read their types
for (int i = 0; i < worksheet.GetCharts().GetCount(); i++)
{
	// Access the chart
	Chart ch = worksheet.GetCharts().Get(i);

	//Get the chart type
	ChartType chartType = ch.GetType();

	//Convert chart type enum to string
	U16String strChartType = u"";

	switch (chartType)
	{
	case Aspose::Cells::Charts::ChartType::BoxWhisker:
		strChartType = u"BoxWhisker";
		break;

	// Change the title of the charts as per their types
	U16String strTitle = u"Chart Type is " + strChartType;
	ch.GetTitle().SetText(strTitle);
}

// Save the workbook
workbook.Save(outputReadAndManipulateExcel2016Charts);
