How to include labels to a plot?
显示 更早的评论
So I have some coordinates and I want to include some labels on my plot.
force = 30;
displacement = [10 20 30 40];
cases = ['This is case 1' 'This is case 2' 'This is case 3' 'This is case 4'];
plot (force, displacement, 'x')
for i =1:length(displacement)
text(force, displacement(i), ['\leftarrow ', cases(i)]);
end
I know the problem is with either line 3 or line 6 because cases is saved as char and when I call cases(i) in line 6 it displays only the individual characters instead of everything that is inside the quotation(' ') marks. Does anyone know how to fix this?

end

Using double quotes creates a string array, where characters enclosed are treated as a single elements.
string_array = "This is case 1";
size(string_array)
Character arrays use single quotes. In this case, each character is treated as a separate element.
character_array = 'This is case 1';
size(character_array)
