Smoothing of series lines in a line graph

You had posted a patch version on the forum, on 2/24/06 at 6:57 am, to fix a problem with the smoothing of lines. Is that fix included in version 3.7.1 ? We purchased 3.7.1 earlier this week.

Yes. Please check it in v3.7.1.

I checked in v 3.7.1. It does not appear to be working, as the lines are not smoothed out - they look just like the evaluation copy that we had before. Here is a screenshot. My code is somewhat like this, and the ChartType is "ChartType.Line":

for (int i = 0; i < chart.NSeries.Count; i++)



chart.NSeriesIdea [I].Smooth = true;


Please remove old reference to aspose.cells.dll in your project and re-add reference to v3.7.1.

I tried the following sample code and it works fine. You can try it in your machine.

Excel excel = new Excel();


int index = excel.Worksheets[0].Charts.Add(ChartType.Line, 10, 4, 22, 8);
Chart chart = excel.Worksheets[0].Charts[index];
chart.NSeries.Add("A1:B3", true);

for(int i = 0; i < chart.NSeries.Count; i ++)
chart.NSeriesIdea [I].Smooth = true;
