matlab - 使用 `text` 绘图时如何包装字符串？

Question

我有一个很长的字符串，我想将其作为描述性文本添加到子图中。

description = 'This kitchen has white cabinets and two blue chairs. The upper cabinet has a black microwave. The paper towels are above the trash can. There is a black garbage can just on the left of the blue chair. On its left there is a red fire distinguisher.';

我尝试在每个句子后添加换行符以使其更合适。

subplot(1,2,2);
with_new_lines = regexprep(description, '\.', '\.\n');
text( 0.5, 0.5, with_new_lines, 'FontSize', 14', 'FontWeight', 'Bold', ...
    'HorizontalAlignment', 'Center', 'VerticalAlignment', 'middle' ) ;

但它仍然不能正确地适合轴。

有没有办法动态包装字符串以适合子图？

Answer 1

在关闭 FitBoxToText 属性的情况下使用注释框怎么样？

description = 'This kitchen has white cabinets and two blue chairs. The upper cabinet has a black microwave. The paper towels are above the trash can. There is a black garbage can just on the left of the blue chair. On its left there is a red fire distinguisher.';
figure;subH=subplot(1,2,2);
pos=get(subH,'Position');
annotation('textbox', pos,...
  'String', description,...
  'FitBoxToText','off');

您可以通过更改 pos 的前两个元素来更改位置，这(我认为)描述了左下角，但忘记了。
