Here is my issue: The Following code plots numbers as text on a Figure that already has points.
for k=1:length(temps)
sss=ss(k);
ht = text(tempx{k}, tempy{k}, num2str(sss),'Parent',ha);
end
The issue is that the array (ss) contains numbers and "NaNs" in it. The array is a 1X55 double that looks like this: ss = [1 5 3 8 3 9 NaN 0 3 5 NaN etc]
because of the fact that the elements of ss are matched with the elements in tempx and tempy, I cannot just remove the []'s.
Does anyone know how to plot ss paired with the tempx/tempy's but without the NaN's?
Appreciate it, Charles

for k=1:length(temps)
sss=ss(k);
if ~isnan(sss)
ht = text(tempx{k}, tempy{k}, num2str(sss),'Parent',ha);
end
end

Can you not just use isnan to check if its a nan
if ~isnan ( ss(k) )
% do your plotting?
end
