DataMatrix

Display a color-coded image of a data matrix with programmable data-tips & click callbacks

DATAMATRIX(data) accepts a numeric or logical data matrix (0, 1 or 2D) and presents it in a color-coded image. Complex data is supported by color-coding the data's complex modulus (magnitude). NaN elements are assigned a specific shade of gray to distinguish them.

The user can specify optional labels, as well as data-tips and/or click callbacks for any or all matrix cells. These optional parameters can be specified either directly, or via order-indifferent case-insensitive property-value pairs, or a combination of both.

Supported properties include: x/y title, x/y labels & rotation (orientation), cell data-tips, cell callbacks, min/max data clamping, reference color (see extensive help within).

Users may use this submission either as-is, or as a learning tool to study data-tip & click callback customizations (including some undocumented version-related quirks/hacks).

Warning:
This code relies in part on undocumented and unsupported Matlab functionality. It works on Matlab 6+, but use at your own risk! Some features (e.g., data-tips) are unavailable on very old Matlab versions.
