PlotArea Property (IChart)

Gets the plot area where the chart data is plotted. Read-only.
ReadOnly Property PlotArea As IChartFrameFormat
Dim instance As IChart
Dim value As IChartFrameFormat
value = instance.PlotArea
IChartFrameFormat PlotArea {get;}
The plot area on a 2-D chart contains the data markers, grid lines, data labels, trend lines, and optional chart items placed in the chart area. The plot area on a 3-D chart contains all the above items plus the walls and floor. The plot area is surrounded by the chart area.
The following code illustrates how to access IChartFrameFormat using PlotArea property and set foreground color for the chart's PlotArea.
using Syncfusion.XlsIO;
class Program
    static void Main(string[] args)
        using (ExcelEngine excelEngine = new ExcelEngine())
            //Create worksheet
            IApplication application = excelEngine.Excel;
            application.DefaultVersion = ExcelVersion.Excel2013;
            IWorkbook workbook = application.Workbooks.Create(1);
            IWorksheet sheet = workbook.Worksheets[0];
            //Add data
            sheet.Range["A1"].Text = "Jan";
            sheet.Range["B1"].Text = "Feb";
            sheet.Range["C1"].Text = "Mar";
            sheet.Range["A2"].Value = "10";
            sheet.Range["B2"].Value = "20";
            sheet.Range["C2"].Value = "30";
            //Create chart
            IChart chart = sheet.Charts.Add();
            //Set range
            chart.DataRange = sheet.Range["A1:C2"];
            //Set chart frame format
            IChartFrameFormat frameFormat = chart.PlotArea;
            //Set color
            frameFormat.Fill.ForeColor = System.Drawing.Color.Red;
            //Save and Dispose
