Create a Basic LineWithDataMarkers Chart
The following example shows how to create a simple LineWithDataMarkers chart that plots monthly sales data.
What the code does
- Creates a workbook and populates it with month‑wise sales data.
- Adds a LineWithDataMarkers chart positioned below the table.
- Links the series to the sales range and assigns month names as categories.
- Saves the file as LineWithDataMarkers_Basic.xlsx.
Run the program and open the generated workbook – you will see a line chart where each data point is highlighted by a default circular marker.
Customize Markers in a LineWithDataMarkers Chart
The default markers may not always match your design requirements. This example demonstrates how to change marker shape, size, fill color, and border.
Customization Highlights
| Property | Effect |
|---|---|
MarkerStyle | Sets the visual shape (e.g., Diamond, Square, Circle). |
MarkerSize | Controls the size in points (default 8). |
Area.ForegroundColor | Fills the marker with the chosen color. |
Border properties | Define the outline color, visibility, and line style. |
Running the program produces LineWithDataMarkers_Customized.xlsx where each profit point is displayed as a green diamond with a dark‑green border, making the data stand out.
