How would I get the text from a textarrow annotation to align with the start of a line. I am unclear how to control the textbox aspect of the textarrow.

    plot(1:100)
    obj.h_line = annotation('line',[0.5 0.5],[0.1 0.8],'Color',0.5*ones(1,4));
    %https://www.mathworks.com/matlabcentral/answers/93858-how-can-i-rotate-a-textbox-annotation-in-matlab-7-9-r2009b
    %What do I put here for x & y????? Do I need to modify another property?
    obj.h_text = annotation('textarrow',[0.5 0.5],[0.1 0.5],'string',...
                    'textarrow annotation', 'HeadStyle','none','LineStyle',...
                    'none', 'TextRotation',90);

I want something like the following, except with the letters rotated so that the tops of the letters touch the line.

Are you looking for something that looks like this?

 obj.h_text = annotation('textarrow',[0.5 0.8],[0.5 0.8],'string',...
                    'textarrow annotation', 'HeadStyle','none','LineStyle',...
                    'none', 'TextRotation',90);

Almost, but the text is not at the bottom of the line. When I make the alignment left, it shifts the text left on the screen, not down (which I would expect after a 90 degree rotation.
