How to add title to plot annotation

I am making a histogram plot to represent data but I am unable to add a title to my annotation textbox. I am able to add a title to my legend with the following code:

lgd1 = legend('Histogram','Mean of Percent Burial','Critical Percent Burial');
lgd_title1 = title(lgd1,'Legend');

This creates a very nice bolded title in the legend and break line between the title and the legend entries. However, similar syntax seems to not work with annotations:

annot1 = annotation('textbox',dim1,'String',str1,'FitBoxToText','on');
annot_title1 = title(annot1,'Results');

The code for the annotation works fine, but using the title function does not work with the following error message:

Unrecognized function or variable 'annot1'.

Is it is possible to include an annotation title similar to legend titles? Or some other work around for this issue.

It's not clear what you are trying to do. The 'string' property of an annotation is the title or label for the annotation line. Are you thinking of something different? Perhaps explain with a sketch.

BTW, the first argument of the title function, as you've used it, is a handle to an axis, not a handle to an annotation.

@Scott MacKenzie, if you execute the first example, you will see that it produces a title for the legend. I assume @Brendan Green is hoping for a similar title for their annotation.

plot(magic(3))
lgd1 = legend('Histogram','Mean of Percent Burial','Critical Percent Burial');
lgd_title1 = title(lgd1,'Legend');

Apologies for the confusion. The code for the legend title works just fine as @the cyclist has shown, however I am trying to add a title to the annotation textbox as shown below. It seems this may not be possible to do as easily for an annotation textbox.

@the cyclist ah yes. Thanks for the clarification. The handle argument for the title function, if used, is a handle to an object capable of receiving a title. That might be an axis (my response) but it could also be a legend, and maybe some other types of objects. But, it cannot be an annotation, since annotations have no such property.

The textbox annotation object does not have a title property, as far as I can tell.

The first work-around that springs to mind is to create a second textbox annotation for the title.
