MATLAB: Matlab legend wont match graph

legendplot

Hi, I have read some of the previous solutions on this problem but they so far haven't worked for me. I cannot get the legend to replicate the colours of the graph itself. A solution I saw on another thread said I should make sure the whole matrix is being plotted, by incorporating (1,:) afterwards. This didn't work for me as it meant some lines wouldn't plot at all.
Any suggestions would be greatly appreciated!

Best Answer

See if this slight modification does what you want: 
legend([h1(1), h2(1), h3(1), h4(1), h5(1), h6(1), h7(1), h8(1)],'Solar Array 1','Solar Array 2','RTG1','RTG2','Mission 1','Mission 2','Mission 3','Mission 4')
