.netCHARTING v10.5 Documentation
Analysis Engine

Introduction

The .netCHARTING analysis engine provides many statistical calculations and financial indicators allowing quick and accurate analysis of your data.

 

Getting Data

The first step is to get a series of data to analyze. Please see the following tutorials as a reference on data acquisition.

The features discussed in this section require that series objects are populated with elements. This does not happen automatically if the DataEngine is not used. Please see this kb for more information.

 

Calculated series and financial indicators often use multiple chart areas. For more info, see:

 

Analysis Engine

Three classes provide the methods used for analysis.

 

The following code snippet demonstrates calculating the mean of a series collection. 

[C#]

...
SeriesCollection mySeries = ...; // Original seriesCollection
Series resultSeries = StatisticalEngine.Mean(mySeries);




Chart.SeriesCollection.Add(resultSeries);
[Visual Basic]

...
Dim mySeries As SeriesCollection = ...(seriesCollection)... ' Original seriesCollection
Series resultSeries = StatisticalEngine.Mean(mySeries)


Chart.SeriesCollection.Add(resultSeries)
Many samples are available under the Features / Analysis Engine section that demonstrate this functionality.

 

ForecastEngine

The forecast engine contains a set of simple methods to perform common forecasting operations. However, the class also contains an advanced set of methods for users familiar with the mathematical formulas.

 

IndicatorOptions

Both analysis classes contain a static Options class that provides additional options for use with the analysis engine.

  • PopulateSubValues
    When a series is calculated down to a single element, the element values of the original series can be included in the resulting element as SubValues.
    A similar feature is also available in the dataEngine: PopulateDateGroupingSubValues Property
  • MatchColors
    Gets or sets a value that indicates whether calculated elements will use the same colors that are assigned to original series. Both, the original and derived data objects must be placed on the same chart to enable this feature because colors are generally based on a palette at runtime.

The following sample demonstrates using the statistical engine's indicator options.

 
[C#]

...
SeriesCollection mySeries = ...; // Original seriesCollection


StatisticalEngine.Options.PopulateSubValues = true;
Element resultElement = StatisticalEngine.Mean(mySeries);

Chart.SeriesCollection.Add(resultElement);
[Visual Basic]

...
Dim mySeries As SeriesCollection ... // Original series

StatisticalEngine.IndicatorOptions.PopulateSubValues = True
Element resultElement = StatisticalEngine.Mean(mySeries)

Chart.SeriesCollection.Add(resultSeries)
