'Shape Outline' property of the Chart


I want to change a chart outline. In Excel, it’s ‘Shape Outline’ property (Chart Tools -> Format -> Shape Styles -> Shape Outline).

I found the same property for shapes and images. A chart has a property with the same name as a shape (‘LineFormat’), but it does not change what I need. I did not find What it changes at all.

Could you help me to figure out How to change this property?
I created a simple document with samples of image, shape and chart that has a custom outline. Also I added a sample of my test code.

Workbook _xl = new Workbook(tbFileName.Text);
foreach (Worksheet ws in _xl.Worksheets)
System.Drawing.Color color = System.Drawing.Color.FromArgb(ceColor.Color.A, ceColor.Color.R, ceColor.Color.G, ceColor.Color.B);
double weight = (double)seWeight.Value;

foreach (Picture pic in ws.Pictures) // It works as expected
pic.BorderLineColor = color;
pic.BorderWeight = weight;

foreach (Chart chart in ws.Charts) // It does not make any visible change. How can I change ‘Shape Outline’?
chart.ChartObject.LineFormat.Weight = weight;
chart.ChartObject.LineFormat.ForeColor = color;

foreach (Aspose.Cells.Drawing.Shape shape in ws.Shapes) // It works as expected
shape.LineFormat.Weight = weight;
shape.LineFormat.ForeColor = color;
string str = _xl.FileName + “.ch” + io.Path.GetExtension(_xl.FileName);
if (!string.IsNullOrEmpty(_xl.FileName)) _xl.Save(str);
I use Excel 2010 and Aspose.Cells v7.4.2.0.

Many thanks,

Thanks for your posting and using Aspose.Cells for .NET.

Please try the Chart.ChartArea.Border property to manipulate the shape outline property of the chart shape.

Thank you for help!
