Create a Custom Excel Chart with C++

// create a new workbook
Workbook workbook;

// get first worksheet which is created by default
Worksheet worksheet = workbook.GetWorksheets().Get(0);

// add sample data
worksheet.GetCells().Get(u"A1").PutValue(50);
worksheet.GetCells().Get(u"A2").PutValue(100);
worksheet.GetCells().Get(u"A3").PutValue(150);
worksheet.GetCells().Get(u"A4").PutValue(110);
worksheet.GetCells().Get(u"B1").PutValue(260);
worksheet.GetCells().Get(u"B2").PutValue(12);
worksheet.GetCells().Get(u"B3").PutValue(50);
worksheet.GetCells().Get(u"B4").PutValue(100);

// add a chart to the worksheet
int chartIndex = worksheet.GetCharts().Add(Aspose::Cells::Charts::ChartType::Column, 5, 0, 20, 8);

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

// add SeriesCollection (chart data source) to the chart ranging from A1 to B4
chart.GetNSeries().Add(u"A1:B4", true);

// set the chart type of 2nd NSeries to display as line chart
