%% Control Error Bars Lengths in All Directions % Display both vertical and horizontal error bars at % each data point. Control the lower and upper lengths of the vertical % error bars using the |yneg| and |ypos| input argument options, % respectively. Control the left and right lengths of the horizontal error % bars using the |xneg| and |xpos| input argument options, respectively. x = 1:10:100; y = [20 30 45 40 60 65 80 75 95 90]; yneg = [1 3 5 3 5 3 6 4 3 3]; ypos = [2 5 3 5 2 5 2 2 5 5]; xneg = [1 3 5 3 5 3 6 4 3 3]; xpos = [2 5 3 5 2 5 2 2 5 5]; errorbar(x,y,yneg,ypos,xneg,xpos,'o')
