File Information

Description

Similar to the well known colorbarf but more realistic.

There are two things missing in colorbar and colorbarf:
1. the colorbar ticks are scaled according to the size of each interval.
2. when color is saturated at the upper limit, or when is white, below the lower limit, a triangle is added. The triangle means "more/less than". Such information is not provided by the existing tools, colorbar and colorbarf.
See the examples.

Besides, there is a bug (?) with contourf: in some cases, even with the levels specified, one additional level is added and corrensponds to the sourrounding line! In such case, colorbarf adds one box for this fake level!

Syntax: H=CBARF(DATA,LEVELS,MODE,SCALE)

Updated 13-7-2007 by adding the option SCALE for linear/non linear scale

19 Jul 2007	Lucio Rezende	grande martinho ! excelente !
02 May 2008	K Kats	I have been thinking about switching to another tool for contour plots, but this neat script saved me! Thank you.
14 May 2008	wu only	Thank u for your work! but I also find a bug(?) with it. cbarf(data,lev,'vertical','nonlinear') and cbarf(data,lev,'vertical','linear') produce different colors according to the same specified levels. The latter one is right.
14 May 2008	M MA	You are right Wu. The bug is now fixed. Thank you
22 May 2008	Wu Zhiyong	Great work! Thank you!
06 May 2009	Brian Magi	A really useful function for a much better colorbar option. This is probably a simple change, but i don't know enough about handle graphics. When i change the position of the colorbar from cbarf to somewhere in the plot, cbarf is always behind the main plot. I tried changing 'Layer' to top (and the main plot to bottom) but to no avail. if anyone has what is probably a quick solution, i'd appreciate it.
29 Sep 2009	Chamane	great work!
