How can I plot multiple signals in a single plot? Please give me suggestions which functions have used for this.

Answer 1

[Chunru]

% Generate som data
fs = 1000; 
t=(0:1/fs:1)';
f = 10:10:40;
x = sin(2*pi*t*f);
x = x + 0.1*randn(size(x));
n = size(x, 2);  % num of channels

yyaxis left
s = 0.4;        % scale factor
plot(t, s*x + (0:n-1) );
yticks(-1:n)
yticklabels(["" "abc" "def" "a" "b" ""])

yyaxis right
ylim( [-1 n]/s)
yticks( [0 1]/s)

Thanks a lot sir.

Sir,

How can I use different signals plot in this type? For example of my given plot.

Please , plot this three signals as like your code. Thank you.

x=sin(2*pi*f*t);

y= cos(2*pi*f*t);

z= tan(2*pi*f*t);

[Dyuman Joshi]

You club the dependent variables together and plot against the independent variable -

%Random data
t = linspace(0,100,1000);
f = 0.025;

x = sin(2*pi*f*t);
y = cos(2*pi*f*t);
z = x.*y;

plot(t, [x;y;z])
legend({'sin', 'cos', 'sin*cos'})

Dear experts, how can I plot in this type? Which function is used for this plotting?

[Dyuman Joshi]

@Walter Roberson has already mentioned a function below. Did you try that?

See stackedplot

Thanks a lot .

How can I plot multiple signals separately as like mentioned figure for avoiding this three signals overlapping?

My goal is to plot this type : here signal gap between another signal is 35

My experimental output plot is:

[Walter Roberson]

Create a timetable() object with variable names {'Input Signal', 'Clean Signal', 'Artifact'} and with 'RowTimes' set to the time vector.

Now stackedplot() that timetable object.

For example,

TT = timetable(input_signal(:), clean_signal(:), artifact(:), 'VariableNames', {'Input Signal', 'Clean Signal', 'Artifact'}, 'RowTimes', t);
stackedplot(TT);

Thank you so much sir.
