Basic Information on varplt
Task: varplt
Purpose: Plot and list variables.
Categories: plotting
VarPlt is a MIRIAD task which plots and lists variables from a
uv file.
Key: vis
The name of the input data-set. No default.
Key: device
The PGPLOT plotting device to use. The default is no plot.
Key: log
The log to give a listing of the variables. The default is no log.
Key: xaxis
Variable to plot on the X axis. Default is "time".
Key: yaxis
Variable to plot on the Y axis. No default.
Key: nxy
Number of plots in the x and y directions. The default varies.
Key: xrange
The min and max range along the x axis of the plots. The default
is to autoscale. Note that for "time" should be given in normal Miriad
time format (either absolute time or time-of-day).
Key: yrange
The min and max range along the y axis of the plots. The default
is to autoscale. Note that for "time" should be given in normal Miriad
time format (either absolute time or time-of-day).
Key: options
Extra processing options. Several can be given, separated by
commas. Minimum match is used.
"dtime" If the x-axis is "time", plot the time in fractions
of a day. The default is to plot in hh:mm:ss.
"compress" If the variable is a 2D array of values, average
the variables along the second dimension.
"overlay" By default, when a variable takes on several values,
each is plotted on a separate plot. The overlay
option makes a single plot.
"unwrap" Unwrap the phases on the yaxis variable. Cannot unwrap
an xaxis variable. By default phases are not unwrapped.
