Libraries.Compute.Statistics.Charts.HistogramCreator

This class is used to create a histogram for use in an application. By default, it uses the Freedman-Diaconis rule for bin widths, which provides a reasonable looking histogram in most cases. More information can be found at: https://en.wikipedia.org/wiki/Freedman%E2%80%93Diaconis_rule

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Charts.HistogramCreator

    DataFrame frame
    frame:Load("Data/Data.csv")

    //Create a Bar Chart and set some properties
    DataFrame frame
    frame:Load("Data/Data.csv")

    HistogramCreator creator
    creator:SetValueColumn("DRT")

    Chart chart = frame:CreateChart(creator)

    chart:SetTitle("Histogram")
    chart:SetYAxisTitle("Frequency")
    chart:SetXAxisTitle("DT")

    //we might then add this chart to a gam

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 (smalle

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(

Obtains what the bin width wa

Returns the name of the value column specifie

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode

This returns the number of ticks to present on the chart.

Manually changes the bin widt

Sets the name of the name column specifie

This sets the number of ticks to present on the chart.
