C# Using EPPlus to draw a chart in Excel RRS feed

  • Question

  • In C# I am using EPPLus to draw a graph in the Excel.

    I have data say

    P1_Value : 22,43,56,87
    P2_Value : 9,2,7,5
    My Requirement

    I need to plot the different coordinates {(22,9),(43,2),(56,7),(87,5)} on the graph.

    Currently my code plots P1_Value against  P2_Value taking P2_Value as Category instead of as numbers. So the X-Axis values do not have sequential values. but it appears as 9,2,7,5 on the X-Axis.

    My Current Code

      ExcelLineChart lineChart = workSheet.Drawings.AddChart("lineChart", eChartType.Line) as ExcelLineChart;
            lineChart.Title.Text = GraphTitle;
             var rangeLabel = workSheet.Cells["D2:D2571"];
             var range1 = workSheet.Cells["C2:C2571"];
            lineChart.Series.Add(range1, rangeLabel);
            lineChart.Series[0].Header = workSheet.Cells["A1"].Value.ToString();
             lineChart.Legend.Position = eLegendPosition.Right;
            lineChart.SetSize(600, 300);
            lineChart.SetPosition(5, 0, 1, 0);

    Any help\pointers are really appreciated. Thanks in advance.

  • You want to make a Scater chart, not a line chart.

    So use eChartType.XYScatterLines as parameter and ExcelScatterChart as cast and variable type.

  • @boothwine Thanks a lot.

    Changing to scatter graph did the work.
