this will help If you store physical dimensions of an object, that is far away from anything which a spatial datatype tries to represent. Spatial Datatypes are for LocationInformation (e.g. Points on globe or Points on a plane) and contain x and y values for geometry data (describing local spaces, like Football fields) or longitude and latitude (describing global spaces)

Make div with opacity:0 have no physical dimensions

should help you out I have a terrific solution which I use often. On the element with opacity: 0 put pointerevents: none. It will still have the dimensions, but it will be as if all events are inactive. Then when you want it to be opacity: 1, return pointerevents to auto. This is the next best thing to using display: block/none but it can be transitioned!

I hope this helps you . Simply use np.broadcast_to for a view  code :
In [142]: arr = np.array([0.0, 0.0, 1.0])
In [144]: np.broadcast_to(arr,(2,3,3))
Out[144]:
array([[[0., 0., 1.],
[0., 0., 1.],
[0., 0., 1.]],
[[0., 0., 1.],
[0., 0., 1.],
[0., 0., 1.]]])
In [148]: arr = np.random.rand(300)
In [149]: %timeit np.broadcast_to(arr,(200,300,300))
100000 loops, best of 3: 3.13 µs per loop
In [174]: np.tile(arr,(2,3,1))
Out[174]:
array([[[0., 0., 1.],
[0., 0., 1.],
[0., 0., 1.]],
[[0., 0., 1.],
[0., 0., 1.],
[0., 0., 1.]]])

How to convert array from (x,y)(z) dimensions into (x,y) dimensions?

will help you Each element of the Bloomberg array is returning 2 sets of data. The key is to have your array have double the number of elements of the top level Bloomberg array. code :
Sub ConvertBloombergTestData()
Dim r As Variant
r = getBloombergTestData
Dim Values As Variant
Dim n As Long
Dim j As Long
Dim Item
ReDim Values(1 To (UBound(r) + 1) * 2, 1 To 2)
For n = LBound(r) To UBound(r)
j = j + 1
Item = r(n, 0)
Values(j, 1) = Item(0)
Values(j, 2) = Item(1)
Item = r(n, 1)
j = j + 1
Values(j, 1) = Item(0)
Values(j, 2) = Item(1)
Next
End Sub
Sub Test()
Dim r As Variant, Values As Variant
r = getBloombergTestData
Values = ConvertBloombergArrayTo2d(r)
End Sub
Function ConvertBloombergArrayTo2d(BloombergArray)
Dim Map As New Collection
FlattenArray Map, BloombergArray
Dim Results As Variant
ReDim Results(1 To Map.Count / 2, 1 To 2)
Dim n As Long, j As Long
For n = 1 To Map.Count Step 2
j = j + 1
Results(j, 1) = Map.Item(n)
Results(j, 2) = Map.Item(n + 1)
Next
ConvertBloombergArrayTo2d = Results
End Function
Sub FlattenArray(Map As Collection, Element As Variant)
If Right(TypeName(Element), 2) = "()" Then
Dim Item
For Each Item In Element
FlattenArray Map, Item
Next
Else
Map.Add Element
End If
End Sub
