Range of Sharex option for muliple plots

I have lakhs of data points and I am trying to create a histogram for 15 subplots, but I am not able to constrict all data points for 15 subplots. I am not understanding how it is selecting a shared range of all 15 subplots. I’m stuck here. Anyone, please help.

Hi @Lionel_Lawrence, can you please add your code?
