Miscellaneous HPLOT functions.

/GRAPHICS/MISC/NEXT

Clear the screen. Initialize a new HIGZ picture if option ZFL or ZFL1 has been selected. Select the Normalisation Transformation number 1 (cm).

/GRAPHICS/MISC/CLR

Clear the screen.

/GRAPHICS/MISC/LOCATE [ ntpri chopt wkid ]

NTPRI	C	Transformation with highest priority D='-1'
CHOPT	C	Options D='R'
WKID	I	Workstation identifier D=1

CHOPT:

'R'	Request mode is used to locate the points (default)
'S'	Sample mode is used to locate the points
'I'	Integrate an histogram between 2 bins
'+'	Use the tracking cross (default is cross-hair)
'T'	The output is done on the terminal.

Locate points on the screen using the graphics cursor and output coordinates on terminal. Control is returned when the BREAK (right) mouse button is clicked (or CRTL/E) or when 20 points are located. The optional parameter NTPRI may be specified to locate a point in the specific transformation number NTPRI. NTPRI=-1 (default) means that all the histogram transformation numbers (10, 20, etc.) have priority on transformation number 1. WKID allows to define in which window the locator is performed.

Note: With the Motif version of PAW the locator is automatically invoke when the mouse cursor enter the window.

/GRAPHICS/MISC/VLOCATE vecx vecy [ chopt ntpri wkid ]

VECX	C	Vector for coordinates X
VECY	C	Vector for coordinates Y
CHOPT	C	Options D=' ' Minus
NTPRI	I	Transformation with highest priority D=-1
WKID	I	Workstation identifier D=1

CHOPT:

'' ''	Use the cross-hair
'+'	Use the tracking cross
'-'	Use the rubber line
'L'	Connect points by a polyline
'P'	Draw the current polymarker at each point
'*'	Draw a * at each point
'S'	Sample mode is used. Allows to see the coordinates of point before clicking
'Q'	Do not print the number of points entered

Locate a set of points using the graphics cursor. Return corresponding coordinates in vectors X and Y. If vectors X or Y do not exist, they are automatically created. Control is returned when the point is outside picture limits or when the BREAK (right) mouse button is clicked (or CRTL/E). The optional parameter NTPRI may be specified to locate a point in the specific transformation number NTPRI (see LOCATE). WKID allows to define in which window the locator is performed.

/GRAPHICS/MISC/HMOVE

Change the contents of a histogram channel using the cursor. Position the cursor to the channel to be changed, trigger graphics input, position the cursor to the new channel value (a rubber band box is used to visualize the change), trigger graphics input to fix the new value.
