I tried using the semilogy but it doesn't seem to work.is it because the x and y values are both negative and both. x=[-0.0992000000000000 0.291600000000000 -0.0673000000000000 -0.109500000000000 0.322600000000000 -0.159700000000000 -0.121000000000000 -0.120800000000000 -0.139600000000000 0.178600000000000]

y=[-0.139380000000000 0.167300000000000 -0.153700000000000 -0.120200000000000 0.339100000000000 -0.172300000000000 -0.130400000000000 -0.172700000000000 -0.131600000000000 0.362600000000000]
