Matlab Colorbar Ticks


The colorbar does display some log-scale ticks… but the labels displayed do not correspond at all to the value being plotted. I know how to use axvline to get a vertical line marking that point, which is good, and I know how to add annotations onto the graph itself, but is there a way of getting an additional tick mark at that particular x value, in addition to the regular marks?. MATLAB adjusts the x-axis, y-axis, and z-axis so that they have equal lengths and adjusts the increments between data units accordingly. Note that the LooseInset property was first reported on CSSM back in 2007 (also here). That's why you see so much of it. For example, you can narrow the limits and adjust the tick labels to reflect the new limits. They have been extracted from the reference manuals. dll' submission on the MATLAB Central File Exchange to do this on a Windows platform.
