Hi @rormond,
Only the y-axis can be made independent for the trellis layout. I'm not sure what kind of data your x-axis represents, but if you consider a transforming command like timechart it would be very difficult to find a way to automate a data scaling function because timechart is dependent upon the time interval you choose when you ran the initial search, while the y-axis intervals are what are returned. The returned values are easier to parse and scale independently. Trellis isn't designed for the kind of functionality you desire.
Suggestion: You can use the zoom feature to zoom in on an x-axis section on the individual trellis panels. i.e. once you create your trellis layout and save it as dashboard panel, you and other users that you've shared the dashboard with can click and drag to select a section of any of the trellis panels to zoom in on the areas along the x-axis in panels where the data is scrunched up in order to spread it out. the obvious limitation is that you can't save the dashboard in the "zoomed" state.
I hope this helps, I'm sorry my answer wasn't exactly what you were looking for.
Cheers,
Eve
