In the following example, I'm trying to center align the second string of arrcell while keeping the first and third strings aligned to the left
cases = 18;
percent = 0.3;
dim = [0.1 0.5 0.1 0.1];
arrcell = {['there are ',num2str(cases),' cases'],['- - - -'],['the percent is ',num2str(percent)]};
an = annotation('textbox',dim,'String',arrcell,'FitBoxToText','on');
set(an, {'HorizontalAlignment'}, {'left';'center';'left'});
but I get the error
Error using matlab.graphics.shape.TextBox/set
Value cell array handle dimension must match handle vector length.
What is wrong?
This is what I would like to obtain

If it works for on your platform, then you should continue using this code. I tried on macOS using R2018b and R2020a, and in both cases, this code created extra space inside the box.

Unfortunately, such a thing is not supported in MATLAB. The only workaround is to draw each component separately. Check the code in my answer. It is cumbersome, to say the least.
