Dears,
This is my code im getting error in ("chart.ValueAxis.Format.Line.BeginArrowheadStyle = LineArrowheadStyleEx.Triangle;")
PresentationEx pres = new PresentationEx();
SlideEx sld = pres.Slides[0];
ChartEx chart = sld.Shapes.AddChart(ChartTypeEx.ScatterWithMarkers, 50, 0, 600, 500);
chart.ChartData.Series.Clear();
chart.ChartData.Categories.Clear();
int defaultWorksheetIndex = 0;
ChartDataCellFactory fact = chart.ChartData.ChartDataCellFactory;
chart.ValueAxis.Format.Line.BeginArrowheadStyle = LineArrowheadStyleEx.Triangle;
The error is Object reference not set to an instance of an object. Null reference Exception,so can you please provide me with a solution ,by the way im using Aspose.Slides Version 7.0.0.0
Regards ,
Kamel
