How to gradually plot two simultaneous graphs in MATLAB gui?

Hello Everyone,

I am trying to plot two graphs in MATLAB gui simultaneously. Both of these should be plotted at the same time. I have tried looping them in in a single loop but it plots them in the same axes, whereas having two loops makes them plot one after other.

Here's my code:

a = 0:0.01:1;
x = sin(2*pi*3*a);
y = cos(2*pi*a);
figure(1)
for i = 1:length(a)
    plot(a(1:i),x(1:i))
    pause(0.05)
end
figure(2)
for i = 1:length(a)
    plot(a(1:i),y(1:i))
    pause(0.05)
end

Can anyone help me figure out a way to plot them both simultaneously?

a = 0:0.01:1;
x = sin(2*pi*3*a);
y = cos(2*pi*a);

fig1 = figure(1);
ax1 = axes(fig1);
fig2 = figure(2);
ax2 = axes(fig2);

for i = 1:length(a)
    plot(ax1, a(1:i),x(1:i))
    plot(ax2, a(1:i),y(1:i))
    pause(0.05)
end

But like I wrote before, I recommend that you read about animatedline()

It works for normal use but in matlab gui, we use

axes(handles.axes1)

can you tell how can I implement this into what you told?

I have tried

a = 0:0.01:1;
x = sin(2*pi*3*a);
y = cos(2*pi*a);

fig1 = handles.axes1;
ax1 = axes(fig1);
fig2 = handles.axes2;
ax2 = axes(fig2);

for i = 1:length(a)
    plot(ax1, a(1:i),x(1:i))
    plot(ax2, a(1:i),y(1:i))
    pause(0.05)
end

but it gives some errors. Any help would be appreciated.

Thanks a lot, Sir. This was a great help.
