rsl_plotsweep

This procedure plots the radar image for a sweep.

Syntax

rsl_plotsweep, sweep, radar_header [, MAXRANGE=value] [, /NEW_WINDOW] [, TITLE=string] [, WINDOWSIZE=value] [, LIKE_FIELD=string] [, ABOUT_FIELD=string] [, /ADVANCE] [, AZIM_SPOKES=value] [, RANGE_AZIM_SPOKES=value] [, RANGE_RING_INTERVAL=value] [, CHARSIZE=value] [, /BGWHITE]

Arguments

sweep
A sweep structure.

radar_header
Radar header structure. Provides time stamp and radar location.

Keywords

ABOUT_FIELD
A string containing information about the field which will appear in TITLE. This replaces the default field information, which is simply the field type (DZ, VR, . . .).

LIKE_FIELD
A string naming the field type whose color table and value scaling is to be used to plot this data. This keyword is needed only if the field type is not one of those recognized by rsl_plotsweep. Recognized field types are DZ, CZ, ZT, VR, SW, DR, ZD, KD, PH, and RH.

MAXRANGE
Maximum range to be plotted, in kilometers. Default is 220 km unless the radar site is Kwajalein, in which case it is 200.

NEW_WINDOW
Set this to open a new plot window.

TITLE
Title to appear above plot. Default is the site name followed by date and time of scan, the field type, and the elevation angle in degrees.

WINDOWSIZE
Window size in pixels. WINDOWSIZE may be scalar or a 2 element array. If scalar, it specifies both width and height of the window. If an array, the first element is width and the second is height.

ADVANCE
This keyword is passed to IDL's MAP_SET procedure. When set, and !P.MULTI is set, IDL advances to the next plot position in a multiple plots window.

AZIM_SPOKES
The interval in degrees between azimuth spokes. The default is 30 degrees. To prevent display of azimuth spokes, set AZIM_SPOKES to zero.

RANGE_AZIM_SPOKES
Range in kilometers for azimuth spokes, i.e., the range at which each spoke ends. Default is the range of the outermost range ring.

RANGE_RING_INTERVAL
The interval between range rings, in kilometers. Default is 50 km. Set this keyword to zero to turn off range ring display.

CHARSIZE
IDL graphics keyword used to set the character size for axes titles and annotations. Normal size is 1.0, which is the default.

BGWHITE
Set this for white background. Default is black.

Examples

Plot the first sweep of the second field in the radar structure, using a white background for the image.
