我在 Matlab 图中添加了一个数据光标,这是我单击“编辑文本更新函数...”时显示的代码
function output_txt = myfunction(obj,event_obj)
% Display the position of the data cursor
% obj Currently not used (empty)
% event_obj Handle to event object
% output_txt Data cursor text string (string or cell array of strings).
pos = get(event_obj,'Position');
output_txt = {['X: ',num2str(pos(1),4)],...
['Y: ',num2str(pos(2),4)]};
% If there is a Z-coordinate in the position, display it as well
if length(pos) > 2
output_txt{end+1} = ['Z: ',num2str(pos(3),4)];
end
我在这里要做的是将字符“X”、“Y”替换为希腊字符,如“alpha”或“beta”。我怎样才能做到这一点?
谢谢!
