[Octave-bug-tracker] [bug #60897] caxis affected by rectangle and patch graphic without scaled color

[Rik]

Update of bug #60897 (project octave):

                  Status:                    None => Confirmed              
        Operating System:       Microsoft Windows => Any

Follow-up Comment #1:

Confirmed.

I tested on Linux and the same issue is present so I changed the OS to "Any".

The rectangle object in Octave is not a drew graphics primitive, but instead
is mimicked with a patch object.  See the file rectangle.m.

Hence, you are correct that this is a general issue related to patches.  The
logic that autoscales the "clim" property of an axis has to look at the color
data for each relevant object.  My guess is that empty cdata, '[]', is being
equated with 0 rather than having a special case to simply ignore.
