NAME
dvpar -- Edit the parameter set that describes the graphics device.
.ih
USAGE
dvpar
.ih
DESCRIPTION
The 'dvpar' parameter set (pset) specifies device-related parameters.
These include the device name, whether plots should be appended to
existing plots, and the edges of the device viewport--that part of the
display device on which to draw the plot.

Note that this is a parameter set (pset)--not an executable task.  That
means that if the task is invoked by name on the command line, it will
start the 'eparam' task to edit the 'dvpar' parameters.  Individual
parameters may be assigned using CL assignment statements from the
command line, or through the task parameters for 'fieldplot'.

PARAMETERS
.ls (device = "stdgraph") [string]
The graphics device name.  The default, "stdgraph", uses the CL 
environment parameter `stdgraph' to find the device name.  For 
example, if you are using gterm in SunView, you could have set 
`stdgraph=gterm' or `device=gterm'.  To overlay graphics on an image 
display, use an "imd" device, "imdr" for red, "imdg" for green, etc.
.le
.ls (append = no) [boolean]
Append the graph to an existing plot?
.le
.ls (left = 0) [real, min = 0, max = 1]
The NDC coordinates of the left edge of the plot.
.le
.ls (right = 0) [real, min = 0, max = 1]
The NDC coordinates of the right edge of the plot.
.le
.ls (bottom = 0) [real, min = 0, max = 1]
The NDC coordinates of the bottom edge of the plot.
.le
.ls (top = 0) [real, min = 0, max = 1]
The NDC coordinates of the top edge of the plot.
.le
.ls (fill = yes) [boolean]
Fill the viewport?  

If set to "yes", the plot will fill the area specified by
the 'left', 'right', 'bottom', and 'top' viewport parameters.  Otherwise, the
shape of the plot will reflect the aspect of the input data, but will
not be larger than the specified viewport.  Note that this does not
apply to all tasks using the 'dvpar' pset.
.le
.ls (coords) [*gcur]
Graphics cursor file.
This is used if the task supports interaction via the graphics cursor.
.le
.ls (image_coord) [*imcur]
Used if the task supports interaction via the image display cursor.
