Worksheet worksheet = workbook.Worksheets["chartTask5"];
workbook.Worksheets.ActiveWorksheet = worksheet;
// Create a chart and specify its location.
Chart chart = worksheet.Charts.Add(ChartType.Line, worksheet["B2:C8"]);
chart.TopLeftCell = worksheet.Cells["F2"];
chart.BottomRightCell = worksheet.Cells["L15"];
// Display markers and specify the marker style and size.
chart.Series[0].Marker.Symbol = MarkerStyle.Circle;
chart.Series[0].Marker.Size = 15;
// Hide the legend.
chart.Legend.Visible = false;
