Set the axis on one of the graphs to the settings you want. Then right click on the axis and select
Edit==>Copy Axis Settings
Then hold down the CNTL key and select
Edit==>Paste Axis Settings
and the axis settings will be copied to all of your histograms in the Distribution window. Holding down the CNTL key while performing selections in JMP is a universal action, to replicate the action across all similar objects in the window you are working in. (i.e. Resizing graphs, selecting red triangle options, etc.)
