Re-arrange cell accordingly to a sorted vector

Hello,

I am using a bar plot to showcase values from references, so the X axis has no relevance. However I calculate in a non-sorted way the Y value and I get also a cell that references this Y values. So I would like to first sort Y and then sort the legend cell to be sorted in the same way. For example I have this as output

Y =

     3     7     1     2
     
legend =

  1×4 cell array

    {'legend1'}    {'legend2'}    {'legend3'}    {'legend4'}
    

Now I want Y to become Y = 1 2 3 7 and the legends to follow such as in:

newY = sort(Y)

newY =

     1     2     3     7

newLegend = sort(legend)

newLegend =

  1×4 cell array

    {'legend3'}    {'legend4'}    {'legend1'}    {'legend2'}
    

How can I do this? I am using R2020a

utilizde another output of sort(). Note legend() is a function.

[newY, index]=sort(Y)
newLegend=oldLegend(index)
