I'm use these namespaces: Excel = Microsoft.Office.Interop.Excel;
and Microsoft.Office.Tools.Excel;
I need to create a line chart with many short lines, which all will be parallel to the x axis.
I already have written all needed points, which should be connected with line.
y axis values for the several type of lines are the same, not they aren't numbers, they are a sort of name. Eventually this should looks this way:
I tried to do this in my way, but faced some problems seriesCollection
doesn`t work as should, he draws 3 lines, but I can see only last one, 2 previous line become same dot. Here is the code:
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
Excel._Application xlApp = new Excel.Application();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
//add data
xlWorkSheet.Cells[1, 1] = 13;
xlWorkSheet.Cells[1, 2] = 27;
xlWorkSheet.Cells[1, 3] = 22;
xlWorkSheet.Cells[1, 4] = 22;
xlWorkSheet.Cells[2, 1] = 42 ;
xlWorkSheet.Cells[2, 2] = 35;
xlWorkSheet.Cells[2, 3] = 22;
xlWorkSheet.Cells[2, 4] = 22;
xlWorkSheet.Cells[3, 1] = 1;
xlWorkSheet.Cells[3, 2] = 10;
xlWorkSheet.Cells[3, 3] = 4;
xlWorkSheet.Cells[3, 4] = 4;
Excel.ChartObjects xlCharts = (Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(10, 80, 300, 250);
Excel.Chart chartPage = myChart.Chart;
myChart.Select();
chartPage.ChartType = Excel.XlChartType.xlXYScatterLines;
Microsoft.Office.Interop.Excel.Application xla = new Microsoft.Office.Interop.Excel.Application();
Excel.SeriesCollection seriesCollection = chartPage.SeriesCollection();
Excel.Series series1 = seriesCollection.NewSeries();
series1.XValues = xlWorkSheet.get_Range("A1", "B1"); ;
series1.Values = xlWorkSheet.get_Range("C1", "D1");
Excel.Series series2 = seriesCollection.NewSeries();
series2.XValues = xlWorkSheet.get_Range("A2", "B2"); ;
series2.Values = xlWorkSheet.get_Range("C2", "D2");
Excel.Series series3 = seriesCollection.NewSeries();
series3.XValues = xlWorkSheet.get_Range("A3", "B3"); ;
series3.Values = xlWorkSheet.get_Range("C3", "D3");
Don't know how to solve this problem. I think y-axis can't be a text, only numbers. Each line should be another series, I guess.
P.S. Numbers can be represented in any required ways to simplify the work.
UPD: This is how I created this dot chart, I have recorded macros
Sub Dot_chart()

ActiveSheet.Shapes.AddChart2(240, xlXYScatterLines).Select

ActiveSheet.Shapes("Chart 2").IncrementLeft 120.8823622047
ActiveSheet.Shapes("Chart 2").IncrementTop 132.3529133858
ActiveChart.SeriesCollection.NewSeries
ActiveChart.FullSeriesCollection(1).Name = "=List1!$B$23"
ActiveChart.FullSeriesCollection(1).XValues = "=List1!$D$22:$D$23"
ActiveChart.FullSeriesCollection(1).Values = "=List1!$D$24:$D$25"
ActiveChart.SeriesCollection.NewSeries
ActiveChart.FullSeriesCollection(2).Name = "=List1!$B$23"
ActiveChart.FullSeriesCollection(2).XValues = "=List1!$E$22:$E$23"
ActiveChart.FullSeriesCollection(2).Values = "=List1!$E$24:$E$25"
ActiveChart.SeriesCollection.NewSeries
ActiveChart.FullSeriesCollection(3).Name = "=List1!$B$28"
ActiveChart.FullSeriesCollection(3).XValues = "=List1!$D$27:$D$28"
ActiveChart.FullSeriesCollection(3).Values = "=List1!$D$29:$D$30"
End Sub
List1 sheet`s name.
After days of searching I found the solution, hope it will be useful for someone.
