REGIONPLOT Plots a simple box indicating a latitude / longitude region. REGIONPLOT(REGION) draws a latitude / longitue box indicated by REGION on the current axes. REGION is an array with the format [WEST EAST SOUTH NORTH]. Longitudes may either be specified on the interval [-180, 180] or on [0, 360]. By default, longitudes will be converted to [-180,180] unless the region overlaps the dateline, in which case [0,360] will be used. The current axes will be held as the box is plotted, then returned to its previous HOLD state. REGION can also be a cell array of N arrays, each with the format REGION{N}=[WEST EAST SOUTH NORTH]. All N regions will then be plotted. REGIONPLOT is compatible with the M_MAP toolbox, as described below. H=REGIONPLOT outputs the line handle H to the plotted box. __________________________________________________________________ Additional options H=REGIONPLOT returns the graphics handle to the plotted box. REGIONPLOT(REGION,STY) uses style string STY, in the LINESTYLE format, with a default value of STY='k'. REGIONPLOT(REGION,'M_MAP') will work with Rich Pawlowicz's M_MAP package by calling M_PLOT. The additional input parameters can be input together in either order, i.e. REGIONPLOT(REGION,STY,'M_MAP') or REGIONPLOT(REGION,'M_MAP',STY). __________________________________________________________________ See also INREGION, TRAJEXTRACT, TOPOPLOT. 'regionplot --f' generates some sample figures. Usage: regionplot(region); h=regionplot(region,'m_map'); h=regionplot(region,'m_map','2k'); __________________________________________________________________ This is part of JLAB --- type 'help jlab' for more information (C) 2013--2016 J.M.
