How to insert an upward arrow in MATLAB Graph?

Question

I want to insert an arrow showing upward direction in MATLAB? How to do this? Arrows are not included in the marker style in MATLAB documentation?

Answer 1

Arrow can be inserted using text. However, position is required to be given for appropriate placement.

text(0.1,0.7,'\uparrow', 'color' ,'r','FontWeight','bold', 'Fontsize', 16);

text(0.2,0.7,'\downarrow', 'color' ,'r','FontWeight','bold', 'Fontsize', 16);

text(0.3,0.7,'\rightarrow', 'color' ,'r','FontWeight','bold', 'Fontsize', 16);

text(0.4,0.7,'\leftarrow', 'color' ,'r','FontWeight','bold', 'Fontsize', 16);
