## Examples


```cpp
Aspose::Cells::Startup();
Workbook workbook;
Worksheet sheet = workbook.GetWorksheets().Get(0);

Cells cells = sheet.GetCells();
cells.Get(0, 1).PutValue(u"Income");
cells.Get(1, 0).PutValue(u"Company A");
cells.Get(2, 0).PutValue(u"Company B");
cells.Get(3, 0).PutValue(u"Company C");
cells.Get(1, 1).PutValue(10000);
cells.Get(2, 1).PutValue(20000);
cells.Get(3, 1).PutValue(30000);

int chartIndex = sheet.GetCharts().Add(ChartType::Line, 9, 9, 21, 15);
Chart chart = sheet.GetCharts().Get(chartIndex);
//Add series
chart.GetNSeries().Add(u"A2:B4", true);
//Set category data
chart.GetNSeries().SetCategoryData(u"=Sheet1!$A$2:$A$4");
//Applying a dotted line style on the lines of an NSeries
chart.GetNSeries().Get(0).GetBorder().SetStyle(LineType::Dot);
chart.GetNSeries().Get(0).GetBorder().SetColor(Color{ 0xff, 0xff, 0, 0 });
//Applying a triangular marker style on the data markers of an NSeries
chart.GetNSeries().Get(0).GetMarker().SetMarkerStyle(ChartMarkerType::Triangle);
//Setting the weight of all lines in an NSeries to medium
chart.GetNSeries().Get(0).GetBorder().SetWeight(WeightType::MediumLine);

Aspose::Cells::Cleanup();
