Libraries.Interface.Controls.Charts.LineChartWriter Documentation
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)
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)
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)
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
- Libraries.Language.Object: The object to compare to.
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
- Libraries.Language.Object: The to be compared.
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)
GetBackground()
GetChartArea()
GetChartAreaHeight()
This action sets the height (percentage) of the chart area.
Return
number:
GetChartAreaPositionX()
add the meta-data character set
Return
number:
GetChartAreaPositionY()
Generate SVG elements for each piece of the chart
Return
number:
GetChartAreaWidth()
This action sets the width (percentage) of the chart area.
Return
number:
GetChartHeight()
This action sets the height (pixel) of the chart.
Return
integer:
GetChartInformation()
This action writes out the Chart 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.
Return

GetChartTitle()
GetChartWidth()
This action sets the width (pixel) of the chart.
Return
