Libraries.Interface.Controls.Charts.LineChartWriter

The LineChartWriter class is part of the set of writers that allow for Charts to save their representation in the form ScalableVectorGraphics. This class will write out all of the necessary text needed to write out an SVG file that will contain the chart.

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.Interface.Controls.Charts.LineChart
    use Libraries.Interface.Controls.Charts.LineChartWriter
    
    DataFrame frame
    frame:Load("Data.csv")
    frame:SetSelectedColumnRange(0,1)
    LineChart chart = frame:LineChart()
    chart:SetTitle("My Awesome Title")
    chart:SetXAxisTitle("Time")
    chart:Display()

    LineChartWriter writer
    output writer:WriteOutChart(chart)

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)

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)

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action writes out the LineChart by grabbing necessary information from the chart and it will then return all of the necessary text needed to write out an SVG file that will contain the chart.

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.Interface.Controls.Charts.LineChart
    use Libraries.Interface.Controls.Charts.LineChartWriter
    
    DataFrame frame
    frame:Load("Data.csv")
    frame:SetSelectedColumnRange(0,1)
    LineChart chart = frame:LineChart()
    chart:Display()
