How can i use chi2gof to compare histograms ? ( vectors of mean values)

Good morning, i'm sorry my english isn't so good but i try to explain my problem. I have to use chi2gof to compare this vectors :

A=[1.2552 15.7481 39.5089 24.4198 17.6382 1.4299]

B=[0.3491 14.5819 41.5906 27.2684 15.7148 0.4952]

C=[0.1916 8.9986 59.9800 21.2556 9.4331 0.1412] D=[0.0580 2.2906 84.5452 10.8005 2.2607 0.0451] with this:

X=[1.2497 17.9165 36.6577 25.0019 17.3697 1.8045]

Therefore for me X is the expected vector and A,B,C,D are the observed vectors that i have to use for each test (4 tests, i suppose from the 1° to the 4° decreas the likelihood).

Thanks for helping me
