Libraries.Compute.Statistics.Charts.PieChartCreator Documentation

This class is used to create a Pie Chart from columns of data in a DataFrame. There are three ways to make a pie chart from the data frame using this class: 1. One column or one factor: Each unique item will have its own wedge using its frequency as the value. 2. More than one column without a factor: Each column will have its own wedge using its sum as the value. 3. One or more columns with a factor: Sum of all values associated with each factor will be in one wedge.

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Charts.PieChart
    
    DataFrame frame
    frame:Load("Data/Data.csv")
    frame:AddSelectedFactors("Factor")
    frame:AddSelectedColumns("Numerical Column")
    
    PieChart chart = frame:PieChart()
    chart:Display(1200,1000)

Actions Documentation

AddColumn(integer column)

This action adds a value to the end of the input.

Parameters

AddFactor(integer column)

This action adds a value to the end of the input.

Parameters

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Create(Libraries.Compute.Statistics.DataFrame frame)

Parameters

Return

Libraries.Interface.Controls.Charts.Chart

EmptyColumns()

This action empty's the list, clearing out all of the items contained within it.

EmptyFactors()

This action empty's the list, clearing out all of the items contained within it.

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

GetColumn(integer index)

This action gets the item at a given location in an array.

Parameters

Return

integer: The item at the given location.

GetColumnIterator()

This action gets an iterator for the object and returns that iterator.

Return

Libraries.Containers.Iterator: Returns the iterator for an object.

GetColumnSize()

This action gets the size of the array.

Return

integer:

GetFactor(integer index)

This action gets the item at a given location in an array.

Parameters

Return

integer: The item at the given location.

GetFactorIterator()

This action gets an iterator for the object and returns that iterator.

Return

Libraries.Containers.Iterator: Returns the iterator for an object.

GetFactorSize()

This action gets the size of the array.

Return

integer:

GetHashCode()

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

Return

integer: The integer hash code of the object.

IsEmptyColumns()

This action returns a boolean value, true if the container is empty and false if it contains any items.

Return

boolean: Returns true when the container is empty and false when it is not.

IsEmptyFactors()

This action returns a boolean value, true if the container is empty and false if it contains any items.

Return
