If you post your code rather than an image of your code (or upload a *.m file), we can copy & paste it into MATLAB, which makes it much easier for us to help you.

% inside the for loop
Temp(h) = q./(6*k_w)*(r_I.^2) + T_sI
% outside the for loop
Temp(Temp == 0 ) = [];
plot(1000:10000,Temp)
the above lines needs to be changed as shown, since you are plotting a point instead of a matrix

You can otherwise put the plot function command inisde the for loop and plot the results
hold on
for h = 1000:10000
% your code
plot(h,Temp,'ro','MarkerSize',12)
end

The way you have coded this, both h and Temp are going to be scalars (single values) after the loop completes, so there is only one point to plot.
