Hi,

I have several matrices that I am trying to graph on the same plot, except that some of the matrices contain lots of NaN values, so when I plot these matrices they appear as dots (or as a marker if I set it). Is there a way to force matlab to drawn lines between the existing points, without having to recreate the matrices such that no NaN values exist?

Thank you

You can use fillmissing function but then start your line from the first not NAN value.

create_new_var= fillmissing(your_array_with_nan,'linear');% to interpolate for the NAN and create a line 
fid_first_notNAN = find(~isnan(backscatter_db_corrected40), 1);
plot(x, create_new_var(id_first_notNAN:end));
