Libraries.Interface.Controls.Charts.HistogramWriter Documentation

The HistogramWriter 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.Histogram
use Libraries.Interface.Controls.Charts.HistogramWriter

DataFrame frame
frame:Load("Data.csv")
frame:SetSelectedColumnRange(0,1)
Histogram chart = frame:Histogram()
chart:SetTitle("My Awesome Title")
chart:SetXAxisTitle("Time")
chart:Display()

HistogramWriter writer
output writer:WriteOutChart(chart)

Inherits from: Libraries.Interface.Controls.Charts.ChartWriter, Libraries.Language.Object

Actions Documentation

AddChartArea(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

This action adds a white background to the canvas

Parameters

AddLegend(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

This action adds the labels on the y axis

Parameters

AddOrderingList(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

Parameters

AddPatternDefinitions(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

This action adds the patterns to be used on chart elements

Parameters

AddRegressionLines(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

Region Wrapper

Parameters

AddXLabels(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

This action adds the labels on the x axis

Parameters

AddYLabels(Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphics canvas, Libraries.Interface.Controls.Charts.Chart chart)

This action adds the labels on the y axis

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.

Parameters

Return

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

Example

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

Equals(Libraries.Language.Object object)

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

Parameters

Return

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

Example

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