NChartPeakDetector Properties |
The NChartPeakDetector type exposes the following members.
Name | Description | |
---|---|---|
AbsoluteThreshold |
Flag determining if Threshold is absolute (true) or relative (false). The default value is false.
Absolute threshold means that it is given in the same units as the values in the analyzed points.
Relative threshold represents a fraction of |max - min|, where max is the maximal value in the given points array and
min is the minimal one.
So if, for example, min = 0, max = 10, threshold is set to 0.3 and this flag is true, then the actual threshold the
peaks will be search according to will be 0.3.
But if this flag is false, the actual threshold will be 0.3 * (10 - 0) = 3.
Normally it's reasonable to use relative threshold if you don't know the bounds of your values. However, this will
mean an additional scan through the points to determine min and max values, so the processing will take a bit more
time.

FindMax |
Flag determining if peak detector should find up-peaks (true), or not (false). The default value is true. The up-peaks
are defined as peaks laying below the moving average inside the search window.
| |
FindMin |
Flag determining if peak detector should find down-peaks (true), or not (false). The default value is true. The down-peaks
are defined as peaks laying beneath the moving average inside the search window.
| |
StepDimension |
Key of the value that should be interpreted as step dimension. Typically it is NChartValue.X (which is the default
value), however for bar series it should be NChartValue.Y.
| |
Threshold |
Threshold to search the peaks according to. The default value is 0.3. See AbsoluteThreshold for details about how
this value is interpreted.
| |
ValueDimension |
Key of the value that should be interpreted as height dimension. Typically it is NChartValue.Y (which is the default
value), however for bar series it should be NChartValueX.
| |
WindowWidth |
Width (in number of points) of the search window needed to calculate moving average. The default value is 5.
