As you can see in the picture, I'm using the mArrow3 function to show plane's orientation. But, sometimes any dart behaves weird.Or the cones merge together, in conclusion, it does not behave the same all the times.

The code I'm using:

 drawnow;
 xExt = abs(diff(get(gca, 'XLim')));
 yExt = abs(diff(get(gca, 'YLim')));
 zExt = abs(diff(get(gca, 'ZLim')));
 mArrow3([0 0 0],[xExt / 1, 0, 0], 'stemWidth', 2,'color','red','facealpha',  0.1);
 mArrow3([0 0 0],[0, yExt / 1, 0], 'stemWidth',  2,'color','red','facealpha',0.1);
 mArrow3([0 0 0],[0, 0, zExt / 1], 'stemWidth',  2,'color','red','facealpha',0.1);
 text(xExt, 0, 0, 'Vx','FontSize',12);  
 text(0, yExt, 0, 'Vy','FontSize',12); 
 text(0, 0, zExt, 'Vz','FontSize',12);
