How to change Series Name?

[sergiu-gheorghe]

 var chart = (IChart)slide.Shapes.First(sp => sp is IChart && sp.Name == chartName);
 var series = chart.SeriesCollection[i];
 series.Name = "change"; // Cannot change the property as it doesn't have a setter

Is it possible somehow to change the Series Name?

As you noticed, the updating of the series name is not supported yet.

Unfortunately, there is not some light workaround for this, because it leads to manipulating not only presentation. You should also update the underlying Spreadsheet.

OK, thank you for the explanation.

Does the library support loading ChartData from the excel Spreadsheet?

You can read byte array of the underlining Spreadsheet via IChart.WorkbookByteArray, but this helps you only read Spreadsheet data, not update.
