MATLAB: How to make gaps in missing data plot lines

Question

I'm relatively new to matlab, so I don't know if this is an easy question to answer.

How do I make gaps in my plot line where data is missing? Thank you

It would be easier with your data.

One option is to fill the missing entries with NaN values:

x = [1:10  15:20];                                      % Create Vector (11:14 Missing)

y = [rand(1,10)  rand(1,6)];                            % Create Vector (11:14 Missing)
figure
plot(x, y)
grid
dx = (diff([0 x]));                                     % Differences Between Coinsecutive Elements
xnan = nan(1, dx(dx > 1)-1);                            % ‘NaN’ Vector (Fill Missing Elements)
dxi = find(dx > 1);                                     % First Index Of Missing Elements
xc = [x(1:dxi-1) xnan x(dxi:dxi+numel(xnan)+1)];        % Replace Missing Elements With ‘xnan’ Vector

yc = [y(1:dxi-1) xnan y(dxi:dxi+numel(xnan)+1)];        % Replace Missing Elements With ‘xnan’ Vector
figure
plot(xc, yc)
grid

Experiment with your data to get the result you want.
