dear all
i have the following data
x=[-15
-10
-5
0
5
10
15
20
]
y=[ 3.8821 3.9018 3.8821 3.8995
2.1445 2.1505 2.1445 2.1498
1.5362 1.5380 1.5362 1.5383
1.2737 1.2745 1.2737 1.2746
1.1467 1.1473 1.1467 1.1472
1.0816 1.0822 1.0816 1.0817
1.0468 1.0470 1.0476 1.0473
1.0275 1.0278 1.0285 1.0289
]

and i want to plot each column in y versus x in the same figure
it is easy to do this by matlab, BUT because the difference between columns is very low. they appear as one curve although i tried log scale
can anyone help me how to appear this comparison between each column by plotting in matlab.

thank you

Why not plot the difference between each y vector?
