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.
