Graph

A 2D graph where results can be plotted.

Example

app = pf.GetApplication()
app:NewProject()
app:OpenFile(FEKO_HOME..[[/shared/Resources/Automation/startup.fek]])

    -- Add a Cartesian graph and a trace 
    
graph = app.CartesianGraphs:Add()
excitation = app.Models["startup"].Configurations[1].Excitations[1]
excitationTrace = graph.Traces:Add(excitation)

    -- Change properties of the graph 

graph.BackColour = pf.Enums.ColourEnum.LightGrey
graph.Grid.Minor.Visible = true
graph.Grid.Border.Weight = 2

Inheritance

The Graph object is derived from the Window object.

The following objects are derived (specialisations) from the Graph object:

Usage locations

The Graph object can be accessed from the following locations:

Property List

BackColour
The background colour of the graph. (Read/Write Colour)
Footer
The graph footer properties. (Read only TextBox)
GreyscaleEnabled
Set the graph's colour scheme to greyscale. (Read/Write boolean)
Height
The height of the window. (Read only number)
Legend
The graph legend properties. (Read only GraphLegend)
Title
The graph title properties. (Read only TextBox)
Width
The width of the window. (Read only number)
WindowActive
True if this window is the active window. (Read only boolean)
WindowTitle
The title of the window. (Read/Write string)
XPosition
The X position of the window. (Read only number)
YPosition
The Y position of the window. (Read only number)

Collection List

Arrows
The collection of 2D arrows on the graph. (ResultArrowCollection of ResultArrow.)
Shapes
The collection of 2D shapes on the graph. (ResultTextBoxCollection of ResultTextBox.)
Traces
The collection of 2D traces on the graph. (ResultTraceCollection of ResultTrace.)

Method List

AddChartImage (view View, posX number, posY number)
Add a 3D view image to this 2D Graph.
AddChartImageFromFile (file string, posX number, posY number)
Add an image file to this 2D Graph.
BlockGraphRedraws ()
Disables graph redraws for performance purposes. When all the changes to the graph are complete, call UnblockGraphRedraws to re-enable graph updates.
Close ()
Close the window.
Duplicate ()
Duplicate the 2D graph. (Returns a Graph object.)
ExportImage (filename string, fileformat string)
Export the window image at its same size to a specified file.
ExportImage (filename string, fileformat string, imagewidth number, imageheight number)
Export the window image at the given size to a specified file.
ExportTraces (filename string, samples number)
Export the graph traces to the specified tab separated file.
Maximise ()
Maximise the window.
Minimise ()
Minimise the window.
Restore ()
Restore the window.
SetPosition (xposition number, yposition number)
Sets the view position. Note that the view is restored when this function is called.
SetSize (imagewidth number, imageheight number)
Sets the view size. Note that the view is restored when this function is called.
Show ()
Shows the view.
UnblockGraphRedraws ()
Enables graph redraws. This method is used in conjunction with BlockGraphRedraws for performance purposes. The graph is redrawn when this method is called and normals redraws will occur on changes.
ZoomToExtents ()
Zoom the content of the window to its extent.
