NAME

dvpar -- Edit the parameter set that describes the graphics device.

USAGE

dvpar

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

(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.
(append = no) [boolean]
Append the graph to an existing plot?
(left = 0) [real, min = 0, max = 1]
The NDC coordinates of the left edge of the plot.
(right = 0) [real, min = 0, max = 1]
The NDC coordinates of the right edge of the plot.
(bottom = 0) [real, min = 0, max = 1]
The NDC coordinates of the bottom edge of the plot.
(top = 0) [real, min = 0, max = 1]
The NDC coordinates of the top edge of the plot.
(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.

(coords) [*gcur]
Graphics cursor file. This is used if the task supports interaction via the graphics cursor.
(image_coord) [*imcur]
Image cursor file. This is used if the task supports interaction via the image display cursor.
