Can X-axis time display as (converted) string in Graph panel?

We store depth data as time series data inside OpenTSDB. For example, depth 1234.56 feet is converted to time as (3000000000 + depth * 100) seconds.
While we can display the data in Graph Panel correctly, the X-Axis is always showing as time (not friendly readable). Is it possible we can modify the code to at least show those X-Axis grids (and tooltips) with converted back to depth data?

You must have accidentally created the same issue twice? Can X-axis time display as (converted) string in Graph panel

How did that happen? Maybe a bug in the forum software?

Sorry must be me accidentally created the second one when could not find the first one.
