Hello!
I'm wondering if there is a way to easily keep one of the axis as a "sort" axis constraint in merge operations. Here's an example of what is the current behavior:
A = AxisArray(collect(1:11), Axis{:time}(0:0.1:1))
B = AxisArray(collect(12:22), Axis{:time}(1.1:0.1:2.1))
M = merge(B, A) # ideally, I would like to force the time axis to an ascending order
1-dimensional AxisArray{Int64,1,...} with axes:
:time, [1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0 … 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0]
And data, a 22-element Array{Int64,1}:
12
13
14
15
16
17
18
19
20
21
⋮
3
4
5
6
7
8
9
10
11Now, trying sort(M) returns
sort(M)
1-dimensional AxisArray{Int64,1,...} with axes:
:time, [1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0 … 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0]
And data, a 22-element Array{Int64,1}:
1
2
3
4
5
6
7
8
9
10
⋮
14
15
16
17
18
19
20
21
22Hence, the values are sorted, but not the time axis definition.
Ideally, I would like to enforce the :time axis to be the sorting constraint in merge function.
I coded a workaround in a custom merge function which consist of reverting the order of the argument (i.e. merge(B, A) -> merge(A, B)). But I suspect that it only works for 2-input call to merge without a more complex workaround.
Thanks for any help or hint on how it can be done!
