            // Add a chart
            int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 5, 0, 15, 5);
            Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];
            
            // Set chart data range
            chart.SetChartDataRange("A1:A4", false);

            // Configure series fill with gradient
            Aspose.Cells.Charts.Series series = chart.NSeries[0];
            series.Area.FillFormat.FillType = Aspose.Cells.Drawing.FillType.Gradient;
            
            // Demonstrate SetPresetThemeGradient with specified parameters
            series.Area.FillFormat.GradientFill.SetPresetThemeGradient(
                Aspose.Cells.Drawing.PresetThemeGradientType.RadialGradient, 
                Aspose.Cells.ThemeColorType.Accent1);
