Hi,
I want to capture my curve. It works so far but i want that my arrow has a 45 degree angle like in the screenshot below. Thank you.
x1=[0 50 75 100]
y1=[100 75 50 25]
[xb,yb] = stairs(x1,y1);
axis([0 200 0 200])
xlim([0 150])
plot(yb,xb)
text(50,75,'\leftarrow Formular XY')
datacursormode on

Try using annotation():
x1=[0 50 75 100]
y1=[100 75 50 25]
[xb,yb] = stairs(x1,y1);
axis([0 200 0 200])
xlim([0 150])
plot(yb,xb)
x = [.50, .45];
y = [.79, .74];
annotation('textarrow',x,y,'String','Formular XY')

What does it
x = [.50, .45];
y = [.79, .74];
exactly means? Are this coordinates?
