Graphic Trigger Window Controls

This paragraph deals with controls of the Graphic trigger window. Controls allow you to specify in detail when GF_ProjectVX code is supposed to sample the variables added to the Variables window.Graphic trigger window controls act in a well-defined way on the behaviour of the window, regardless for the type of the module (IL, ST, FBD or LD) where the related trigger has been inserted.Window controls are made accessible to users through the Controls bar of the debug window.

Button	Command	Description
	Start graphic trace	When you push this button down, you let acquisition start. Now, if acquisition is running and you release this button, you stop the sample collection process, and you reset all the data you have acquired so far.
	Enable/Disable cursors	The two cursors (red cursor, blue cursor) may be seen and moved along their axis as long as this button is clicked. Release this button if you want to hide simultaneously all the cursors.
	Show samples	This control is used to put in evidence the exact point in which the variables are triggered at each sample.
	Split variables	When clicked, this control splits the y-axis into as many segments as the dragged-in variables, so that the diagram of each variable is drawn in a separate band.
	Show all values	It is used to fill in the graph window all the values sampled for the selected variables in the current record set.
	Horizontal Zoom In and Zoom Out	Zooming in is an operation that makes the curves in the Chart area appear larger on the screen, so that greater detail may be viewed. Zooming out is an operation that makes the curves appear smaller on the screen, so that it may be viewed in its entirety. Horizontal zoom acts only on the horizontal axis.
	Horizontal show all	This control is used to horizontally centre record set samples. So first sample will be placed on the left margin, and last will be placed on the right margin of the graphic window.
	Vertical Zoom In and Zoom Out	Vertical Zoom acts only on the vertical axis.
	Vertical show all	This control is used to vertically centre record set samples. So max value sample will be placed near top margin and low value sample will be placed on the bottom margin of the graphic window.
	Stop acquisition	Not implemented.
	Pause acquisition	Not implemented.
	Restart acquisition	Not implemented.
	Graphic trigger window properties	Pushing this button causes a tabs dialog box to appear, which allows you to set general user options affecting the action of the graphic trigger window. Since the options you can set are quite numerous, they are dealt with in a section apart.Click here to access this section.
	Save chart	Push this button to print both the Chart area and the Variables window.
	Load data (no append)	Not implemented.
	Load data and append	Not implemented.
	Print chart	Push this button to print both the Chart area and the Variables window.

Trigger Counter This read-only control displays two numbers with the following format: X/Y.X indicates how many times the debug window manager has been triggered, since the graphic trigger was installed.Y represents the number of samples the graphic window has to collect before stopping data acquisition and drawing the curves.Trigger StateThis read-only control shows you the state of the Debug window. It can assume the following values.

	No sample(s) taken, as the trigger has not occurred during the current task execution.
	Sample(s) collected, as the trigger has occurred during the current task execution.
	The trigger counter indicates that a number of samples has been collected satisfying the user request or memory constraints, thus the acquisition process is stopped.
	Communication with target interrupted, the state of the trigger window cannot be determined.
