I've tried
output_txt = {[event_obj.Target.Tag]};
but frustratingly, Target gets the whole image rather than the datatip.

Hi Andrew,
It seems like you are trying to show the Tag of the target object in the data tip. One possible solution is to customize DataTipTemplate property of the chart object. Here is an example:
l = plot(1:10,"Tag","I am tag");
% Customize the content of data tip
l.DataTipTemplate.DataTipRows = dataTipTextRow("Tag",repmat(string(l.Tag),numel(l.XData),1));
% Create data tip at index 2 or click to create data tip interactively
d = datatip(l,"DataIndex",2)
You can refer to Create Custom DataTips documentation for more details.
