Anottations are overlapping in each loop interaction
显示 更早的评论
In the following code I am plotting a graph for each loop interaction. I want to put a text box in the graphics window showing a value that varies for each interaction. However, the values in the text box are overlapping. The code is running normally, just run it to see the problem. Does anyone know how to fix this? If someone helps me I'll be very grateful.
close all; clear all; clc;
m = 1; %[Kg] Mass of the oscillating element
Fo = 1; %[N] Intensity of external force
Ao = 1; %[m] Initial amplitude
phi = 0; %phase
Wo = 1; %[1/s]
b = 1;
bc = 2*m*Wo;
tau = m/b;
W = 0:0.1:Wo;
t = 0:0.1:60;
figure;
set(gcf,'color','white')
for i=1:length(W)
u(:,i) = (Fo/(m*abs(Wo^2 - W(i))))*cos(Wo* t + phi) + (Ao*exp(-t/tau).*cos((Wo*sqrt(1 - (b/bc)^2))*t + phi));
pause (1)
plot(t,u(:,i));
grid on
axis([1,65,-40,40])
str = num2str(W(i));
dim = [.75 .5 .3 .3];
annotation('textbox',dim,'String',str,'FitBoxToText','on');
end

Write you for loop like this
a = [];
for i=1:length(W)
u(:,i) = (Fo/(m*abs(Wo^2 - W(i))))*cos(Wo* t + phi) + (Ao*exp(-t/tau).*cos((Wo*sqrt(1 - (b/bc)^2))*t + phi));
pause (1)
plot(t,u(:,i));
grid on
axis([1,65,-40,40])
str = num2str(W(i));
dim = [.75 .5 .3 .3];
delete(a);
a = annotation('textbox',dim,'String',str,'FitBoxToText','on');
end
