How do I plot different array smoothly which contain NaN in same figure

Plot 4 arrays all of them contain NaN value. How do you plot it smoothly.

Here is the code:

lw=2
plot(Sig1,'LineWidth',lw,'Color',[1 0.76 0])
hold on
plot(Sig2,'r','LineWidth',lw)
hold on
plot(Sig3,'g','LineWidth',lw)
hold on
plot(Sig4,'b','LineWidth',lw)
hold off

One option is to use the fillmissing function.

Example —

sig1 = [rand(1,10) NaN];
sig2 = [rand(1,10) NaN];
sig3 = [rand(1,10) NaN NaN];
sig4 = [rand(1,10) NaN];

sigv = [sig1 sig2 sig3 sig4];
sigvfm = fillmissing(sigv, 'linear');

figure
plot(sigv, 'b', 'LineWidth',1.5)
hold on
plot(sigvfm,'r')
hold off.

Make appropriate changes to work with your data.

Strider, Here i attached the 4 arrays .

[Star Strider]

Try this:

D = load('sig.mat');
Sig1 = D.Sig1;
Sig2 = D.Sig2;
Sig3 = D.Sig3;
Sig4 = D.Sig4;

Sig = [Sig1,Sig2,Sig3,Sig4];
Sigfm = fillmissing(Sig, 'linear', 'EndValues','nearest');

figure
subplot(2,1,1)
plot(Sig, 'LineWidth',1)
subplot(2,1,2)
plot(Sigfm, 'LineWidth',1)

producing:

There are a number of options that specify how fillmissing should work. Explore that documentaiton to see what works best for you.

Strider, This isn't what i want. Probably you didn't see my attached file. Each color represents a different array.

[Star Strider]

Much of this is ambiguous.

Try this:

D = load('sig.mat');
Sig1 = D.Sig1;
Sig2 = D.Sig2;
Sig3 = D.Sig3;
Sig4 = D.Sig4;
Sig = [Sig1;Sig2;Sig3;Sig4];                                            % Concatenate
Sigfm = fillmissing(Sig, 'linear', 'EndValues','nearest');              % Fill NaN Values

figure
plot(Sigfm(1,:), 'k', 'LineWidth',1)

producing:
