[praveenkasani]

Can we use the combination of charts in a single slide using Spire.Presentation? For example Pie and Barchart in a single powerpoint slide? Thanks in Advance

Hello,

Thank you for your inquiry.
Yes, our Spire.Presentation does support the creation of combination charts. Please refer to the example code snippet provided below:

Code: Select all

            Presentation presentation = new Presentation();

            //Insert a bar clustered chart
            RectangleF rect = new RectangleF(100, 100, 550, 320);
            IChart chart = presentation.Slides[0].Shapes.AppendChart(ChartType.BarClustered, rect);

            //Set chart title
            chart.ChartTitle.TextProperties.Text = "Monthly Sales Report";
            chart.ChartTitle.TextProperties.IsCentered = true;
            chart.ChartTitle.Height = 30;
            chart.HasTitle = true;

            //Create a datatable
            DataTable dataTable = new DataTable();
            dataTable.Columns.Add(new DataColumn("Month", Type.GetType("System.String")));
            dataTable.Columns.Add(new DataColumn("Sales", Type.GetType("System.Int32")));
            dataTable.Columns.Add(new DataColumn("Growth rate", Type.GetType("System.Decimal")));
            dataTable.Rows.Add("January", 200, 0.6);
            dataTable.Rows.Add("February", 250, 0.8);
            dataTable.Rows.Add("March", 300, 0.6);
            dataTable.Rows.Add("April", 150, 0.2);
            dataTable.Rows.Add("May", 200, 0.5);
            dataTable.Rows.Add("June", 400, 0.9);

            //Import data from datatable to chart data
            for (int c = 0; c < dataTable.Columns.Count; c++)
            {
                chart.ChartData[0, c].Text = dataTable.Columns[c].Caption;
            }
            for (int r = 0; r < dataTable.Rows.Count; r++)
            {
                object[] datas = dataTable.Rows[r].ItemArray;
                for (int c = 0; c < datas.Length; c++)
                {
                    chart.ChartData[r + 1, c].Value = datas[c];

                }
            }

            //Set series labels
            chart.Series.SeriesLabel = chart.ChartData["B1", "C1"];

            //Set categories labels   
            chart.Categories.CategoryLabels = chart.ChartData["A2", "A7"];

            //Assign data to series values
            chart.Series[0].Values = chart.ChartData["B2", "B7"];
            chart.Series[1].Values = chart.ChartData["C2", "C7"];
         

            //Change the chart type of serie 2 to line with Pie
            chart.Series[1].Type = ChartType.Pie;

            //Plot data of series 2 on the secondary axis
            chart.Series[1].UseSecondAxis = true;

            //Set the number format as percentage
            chart.SecondaryValueAxis.NumberFormat = "0%";

            //Hide gridlinkes of secondary axis
            chart.SecondaryValueAxis.MajorGridTextLines.FillType = FillFormatType.None;

            //Set overlap
            chart.OverLap = -50;

            //Set gapwidth
            chart.GapWidth = 200;

            //Save to file
            presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
