Remarks
If a simple series includes multiple points with low values, you may want to reduce their quantity to emphasize the most important points.
Mode and Value properties determine what points the parent series displays as separate slices if the Enabled property is set to True. The series displays all other points as an aggregate slice if the ShowOthers property is set to True (default).
Examples
- Top N is Disabled
This example demonstrates the same series with all points for comparison.
- Count Mode
Default Mode. A simple series displays a number of first points as separate slices according to their order in the Series.Points collection if series points are unsorted. The Value property specifies the number of separate slices.
Note
The current sort order defines what series points are displayed as separate slices in this mode.
In this example, the Series.SortBy property is set to TdxChartSeriesSortBy.Value, and the Series.SortOrder property is set to to soDescending to display the points with highest values as separate slices.
- Relative Threshold Mode
All series points whose values exceed Value (as a percentage)[1] are displayed as separate slices.
- Absolute Threshold Mode
All series points whose values exceed Value[2] are displayed as separate slices.
Refer to the TdxChartSeriesTopNOptionsMode type description for additional information on all available options.
Default Value
The Mode property’s default value is TdxChartSeriesTopNOptionsMode.Count.
