Description
Hi,
I am wondering if there is a way to change axes.
For example,
using Unitful
using AxisArrays
const μm = u"μm"
const s = u"s"
tmp = AxisArray(rand(1000,1000,2,2), (:x, :y, :z, :t), (0.577μm, 0.577μm, 5μm, 2s))
I would like to change 0.577μm of :x to some other values. Is there easy with to change it (without generating a new array)?
I tried several things. All didn't work.
# All below do not work.
tmp[Axis{:x}] = 1:1000
tmp = AxisArray(tmp, (:x), (1))
tmp = AxisArray(tmp, (:x, :y, :z, :t), (1, 0.577μm, 5μm, 2s)) # This generates additional axis.
Best,

Research direction
No source file or test is identified in the issue. Start by reproducing the Julia example with AxisArrays and inspect the documented axis-construction and indexing behavior; the work is done only when the supported way to change the :x axis without generating a new array is established or clearly documented.
