Line Chart

Line charts are the most basic charts that are created by connecting the data points with straight lines. These charts are used to visualize a trend in data by comparing values against periodic intervals such as time, temperature etc. Some examples that can be well depicted using line charts are closing prices of a stock in a given time frame and monthly average sale of a product.

DsExcel supports the following types of line charts.

LineMarkers	LineMarkers chart	LineMarkers chart is used to display data values shown with markers. It is ideal to use this chart when there are many categories or approximate values.
LineMarkersStacked	LineMarkersStacked chart	LineMarkersStacked is used to display data values with markers, typically showing the trend of contribution of each value over time or evenly spaced categories.

Using Code

Refer to the following example code to add LineStacked100 chart:

public void LineCharts()
  {
      // Initialize workbook
      Workbook workbook = new Workbook();
      // Fetch default worksheet 
      IWorksheet worksheet = workbook.Worksheets[0];
      // Prepare data for chart
      worksheet.Range["A1:D4"].Value = new object[,]
      {
           {null, "Q1", "Q2", "Q3"},
           {"Mobile Phones", 1330, 2345, 3493},
           {"Laptops", 2032, 3632, 2197},
           {"Tablets", 6233, 3270, 2030}
      };
      worksheet.Range["A:D"].Columns.AutoFit();
      // Add Line Chart
      IShape lineChartshape = worksheet.Shapes.AddChart(ChartType.LineStacked100, 250, 20, 360, 230);

      // Adding series to SeriesCollection
      lineChartshape.Chart.SeriesCollection.Add(worksheet.Range["A1:D4"], RowCol.Columns, true, true);

      // Configure Chart Title 
      lineChartshape.Chart.ChartTitle.TextFrame.TextRange.Paragraphs.Add("Annual Sales Record");

      // Saving workbook to Xlsx
      workbook.Save(@"21-LineChart.xlsx", SaveFileFormat.Xlsx);
  }
