The Layers Toolbar

This toolbar is only active when a graph window is selected. It provides single-click access to the commands of the Graph menu which can be used in order to create and manipulate multi-layer 2D graphs.

Table 4-16. Layers toolbar commands

Icon	Command	Key	Description
	Add Layer Commands		Selects the last used add layer tool or selects a new one from a drop down list.
	Add Axis Commands		Selects the last used add axis tool or selects a new one from a drop down list.
	Arrange Layers...	Shift-A	Opens a dialog for rearranging all layers of the active graph window.
	Automatic Layout		Automatically rearranges all layers of the active graph window.
	Fit Layers Commands		Selects the last used fit layers tool or selects a new one from a drop down list.
	Extract/Merge Layers Commands		Selects the last used extract/merge layers tool or selects a new one from a drop down list.

Table 4-17. Add Layer Commands

Icon	Command	Key	Description
	Add Layer	Alt-L	Adds a new layer to the active plot window.
	Add Empty Inset Layer		Adds an empty inset layer to the active graph window.
	Add Inset Layer With Curves		Adds an inset layer to the active graph window that contains copies of any curves in the active plot layer.

Table 4-18. Add Axis Commands

Icon	Command	Key	Description
	Add Horizontal Axis		Adds a central horizontal axis to the active plot layer.
	Add Vertical Axis		Adds a central vertical axis to the active plot layer.

Table 4-19. Fit Layers Commands

Icon	Command	Key	Description
	Fit Layers to Window		Adjusts the dimensions of the existing layers to fit the current window size by shrinking them in both horizontal and vertical direction.
	Fit Window to Layers		Adjusts the dimensions of the active 2D plot window in order to entirely display all its layers.

Table 4-20. Extract/Merge Layers Commands

Icon	Command	Key	Description
	Extract to Layers		Extracts datasets (curves) from the active layer onto separate layers.
	Extract to Graphs...		Extracts all layers in the active graph window to separate graphs.
	Merge Graph Windows...		Opens the Graph Manipulation dialog that allows users to choose the graph windows to be merged in a new 2D plot window.
