How to determine if it obeys a chi-square distribution？

Question

I want to determine whether a set of data obeys a chi-square distribution, how do I do this with JMP? Thanks!
I looked at the distribution-continuous fit and didn't find this distribution.

Hi @lehaofeng : The Chi-squared distribution is a special case of the Gamma distribution.

Statistical Details for Continuous Fit Distributions (jmp.com)

So, you could start via trying to fit a Gamma distribution. If it doesn't fit a Gamma, then it can't be a Chi-squared. If, however, it is Gamma...then it might be Chi-Squared. Try that then come back.
