## Examples


```cpp
Aspose::Cells::Startup();
//Instantiating a Workbook object
Workbook workbook;

//Obtaining the reference of the first worksheet
Worksheet worksheet = workbook.GetWorksheets().Get(0);

//Adding a sample value to "A1" cell
worksheet.GetCells().Get(u"A1").PutValue(50);

//Adding a sample value to "A2" cell
worksheet.GetCells().Get(u"A2").PutValue(100);

//Adding a sample value to "A3" cell
worksheet.GetCells().Get(u"A3").PutValue(150);

//Adding a sample value to "B1" cell
worksheet.GetCells().Get(u"B1").PutValue(60);

//Adding a sample value to "B2" cell
worksheet.GetCells().Get(u"B2").PutValue(32);

//Adding a sample value to "B3" cell
worksheet.GetCells().Get(u"B3").PutValue(50);

//Adding a chart to the worksheet
int chartIndex = worksheet.GetCharts().Add(ChartType::PieExploded, 5, 0, 25, 10);

//Accessing the instance of the newly added chart
Chart chart = worksheet.GetCharts().Get(chartIndex);

//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B3"
chart.GetNSeries().Add(u"A1:B3", true);

//Show Data Labels
chart.GetNSeries().Get(0).GetDataLabels().SetShowValue(true);

for (int i = 0; i < chart.GetNSeries().Get(0).GetPoints().GetCount(); i++)
{
    //Get Data Point
    ChartPoint point = chart.GetNSeries().Get(0).GetPoints().Get(i);
    //Set Pir Explosion
    point.SetExplosion(15);
    //Set Border Color
    point.GetBorder().SetColor(Color{ 0xff, 0xff, 0, 0 });
}

//Saving the Excel file
workbook.Save(u"book1.xls");
