NAME

pltpar -- Edit the parameter set that describes plot attributes.

USAGE

pltpar

DESCRIPTION

The pltpar parameters specify the attributes of plots drawn by the sgraph task.

Note that this is a pset, not an executable task; it defines a set of parameters used by other tasks. Invoking the pset by name runs eparam on the parameter set, allowing the user to modify the parameters. Alternatively, the parameters may be modified on the command line by specifying the pset name and parameter name, for example, you can type "pltpar.pointmode=yes" to set only the pointmode parameter. Parameters can also be edited by using eparam on the calling task (e.g., by typing "eparam sgraph"), in which case, pltpar will appear as one of the task parameters; the pltpar parameters may then be edited by positioning the cursor on the line containing the pset name and typing ":e". After editing the pset parameters, type Control-Z (or :q) to return to the main task parameter menu.

PARAMETERS

(stack = no) [boolean]

Stack multiple curves on separate vertical axes?

If this is set to "no", all curves will be scaled together and plotted on a single set of axes. Otherwise a separate set of axes will be drawn, joined into a single vertical column.

(axis = 1) [integer, min = 1, max = 7]

Axis along which projection is to be taken. If the input image has more than one dimension, the data will be projected to a single dimension. This parameter specifies the axis along which projection will occur. The default is one, i.e., project along the X axis.

(pointmode = no) [boolean]

Plot points only?

If set to "no", the task will plot connected curves. Note that to plot error bars, use pointmode = no and erraxis = 1 or 'erraxis = 2'. See the descriptions of the marker and szmarker parameters.

(marker = box) [string, allowed values: point | box | plus |

cross | circle | diamond | hline | vline | hebar | vebar]

The marker style for each plotted point if pointmode=yes. See also szmarker.

(szmarker = 0.005) [real]

The size of the markers if pointmode = yes. If szmarker > 0, use this value as the size in normalized device coordinates (NDC) . If szmarker < 0, use the absolute value as the size in world coordinates (WC). If szmarker = 0 and the input comes from a text file, use the third column in the input data as the marker size. If data are from an image or a table, then szmarker specifies the same size of every point.

(erraxis = 0) [integer, min = 0, max = 2]

Plot the data as error bars?

The following values are allowed:

0 - Plot data as values rather than error bars
1 - Plot data as errors parallel to X axis
2 - Plot data as errors parallel to Y axis

Note that erraxis is ignored if pointmode = yes.

(errtype = bartck) [string, allowed values: tckbar | bar | tick |

limit]

The style of error bars (if erraxis is not zero).

(pattern = solid) [string, allowed values: solid | dashed |

dotted | dotdash]

The line pattern style for the curve or the first of multiple curves.

(crvstyle = straight) [string, allowed values: straight | pseudohist

| fullhist]

The curve style. straight means line segments will connect data points, pseudohist means that horizontal segments will be placed at each value and vertical segments will connect these, fullhist means a bar graph, or horizontal segments at each value with vertical lines connecting the value with the bottom axis.

(rejectlog = yes) [boolean]

Replace invalid logarithmic values with INDEF? Invalid values will be ignored in scaling and plotting.

(barpat ="hollow") [string, allowed values: hollow | solid |

ahatch | bhatch | chatch | dhatch]

Fill pattern for bar plot. The nature of the pattern depends on the device and graphics kernel (driver) used to plot. Many kernels do not support fill patterns.

(crvcolor = INDEF) [integer, min = 1]

Color index of data curve(s). This color applies only to plotted data curves. The color of any axes, labels, etc., is specified by the `color' parameter. Note that the actual, drawn color will depend on the device and graphics kernel (driver) used for plotting. Many kernels do not support color at all. The usual interpretation of the color index is:

    1 -- Black
    2 -- White
    3 -- Red
    4 -- Green
    5 -- Blue
    6 -- Yellow
    7 -- Cyan (blue/green)
    8 -- Magenta (red/blue)

(color = INDEF) [integer, min = 1]

Color index of axis and labels. The color of the data curve(s) is specified by the `crvcolor' parameter. Note that the actual, drawn color will depend on the device and graphics kernel (driver) used to plot. Most kernels do not support color.

(cycolor = no) [boolean]

Cycle colors instead of line style for multiple curves?

If multiple curves are plotted on the same viewport (axes), i.e., stack=no, then use the color specified by the crvcolor parameter for the first curve, and the next available color for each subsequent curve. There are eight available colors, as described in the description of the crvcolor parameter.

(version = 17August92) [string]

Date the task was installed. Do not change this parameter.
