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')
