get.cb.pos: Returns additional colorbar placement information

In oceanmap: A Plotting Toolbox for 2D Oceanographic Data

Returns additional colorbar placement information

Description

Returns colorbar ticks length, label-, cb.title- and cb.xlab-position. ticks.lab, cb.title and cb.lab are horizontally centered, so only the y-value is returned.

Usage

get.cb.pos(cbx,cby,oticks)

Arguments

cbx	the horizontal limits (x1, x2) of the colorbar.
cby	the vertical limits (y1, y2) of the colorbar.
oticks	letter defining alignment of colorbar ticks and labels. Allowed values are: 'b' for bottom, 'l' for left and 'r' for right alignment.
