You can show markers or points in the sparkline graphs. The following image displays the points in a line sparkline. You can specify different colors for low or negative, high, first, and last points.
The high point is the point for the largest value. The low point is the smallest value. The negative point represents negative values. The first point is the first point that is drawn on the graph. The last point is the last point that is drawn on the graph.
The SeriesColor property applies to the line for the line spark type. The MarkersColor property is only for the line type sparkline. See the ExcelSparklineSetting class for a list of sparkline properties and additional code samples.
Return to Using Sparklines.
Using Code
- Specify a cell to create the sparkline in.
- Specify a range of cells for the data.
- Set any properties for the sparkline (such as ShowFirst and FirstMarkerColor).
- Add the sparkline to the cell.
Example
This example creates a line sparkline in a cell and shows different markers and colors.
