+## Description
+
+I want to generate stacked line graphs in Excel using the `FloatingChartShape` feature in Telerik Document Processing's SpreadProcessing library. However, the chart defaults to a stacked line graph with markers instead of a plain stacked line graph. Additionally, I want to configure the X-axis to display dates while the Y-axis displays numerical values when plotting multiple columns of data.
+
+This knowledge base article also answers the following questions:
+- How do I create a stacked line chart in Excel using Telerik Document Processing?
+- How can I plot specific data on the X-axis and Y-axis in an Excel chart?
+- How do I remove markers from a stacked line graph using FloatingChartShape?
+
+## Solution
+
+To create a stacked line graph and configure the axes as desired, follow these steps:
+
+1. Define the `LineSeriesGroup` and set its grouping to `Stacked`. This ensures the graph is created as a stacked line chart.
+
+```csharp
+LineSeriesGroup seriesGroup = new LineSeriesGroup();
+seriesGroup.Grouping = SeriesGrouping.Stacked;
+```
+
+2. Create individual `LineSeries` for each data column. Set the `Values` to represent numerical data and `Categories` to represent dates.
+
+```csharp
+LineSeries lineSeries1 = new LineSeries();
+lineSeries1.Values = new WorkbookFormulaChartData(worksheet, new CellRange(1, 1, 10, 1));
+lineSeries1.Categories = new WorkbookFormulaChartData(worksheet, new CellRange(1, 0, 10, 0));
+lineSeries1.Marker = new Marker();
+lineSeries1.Marker.Symbol = MarkerStyle.None; // Removes markers
+seriesGroup.Series.Add(lineSeries1);
+
+LineSeries lineSeries2 = new LineSeries();
+lineSeries2.Values = new WorkbookFormulaChartData(worksheet, new CellRange(1, 2, 10, 2));
+lineSeries2.Categories = new WorkbookFormulaChartData(worksheet, new CellRange(1, 0, 10, 0));
+lineSeries2.Marker = new Marker();
+lineSeries2.Marker.Symbol = MarkerStyle.None; // Removes markers
+seriesGroup.Series.Add(lineSeries2);
+```
+
+3. Define the axes for the chart. Set the `CategoryAxis` to plot dates and the `ValueAxis` for numerical values.
+
+```csharp
+AxisGroup axisGroup = new AxisGroup();
+CategoryAxis categoryAxis = new CategoryAxis();
+SolidFill lineColor = new SolidFill(new ThemableColor(ThemeColorType.Background2));
+categoryAxis.Outline.Fill = lineColor;
+categoryAxis.MajorGridlines.Outline.Fill = lineColor;
+axisGroup.CategoryAxis = categoryAxis;
+
+ValueAxis valueAxis = new ValueAxis();
+valueAxis.Outline.Fill = lineColor;
+valueAxis.MajorGridlines.Outline.Fill = lineColor;
+axisGroup.ValueAxis = valueAxis;
+```
+
+4. Create the chart and associate the `LineSeriesGroup` and axes with it.
+
+```csharp
+DocumentChart documentChart = new DocumentChart();
+documentChart.SeriesGroups.Add(seriesGroup);
+documentChart.PrimaryAxes = axisGroup;
+```
+
+5. Replace the default chart in the `FloatingChartShape` with the configured `DocumentChart`. Set the dimensions and add it to the worksheet.
+
+```csharp
+FloatingChartShape floatingChartShape = new FloatingChartShape(worksheet, new CellIndex(0, 5), new CellRange(0, 0, 4, 3), ChartType.Line);
+floatingChartShape.Chart = documentChart;
+floatingChartShape.Width = 400; // Set desired width
+floatingChartShape.Height = 250; // Set desired height
+
+worksheet.Charts.Add(floatingChartShape);
+```
+
+By following these steps, you can generate a stacked line graph without markers and configure the axes to display the required data.
