Utilize the power of lodash to group an object by multiple keys simultaneously

Question

Utilize the power of lodash to group an object by multiple keys simultaneously

The information is structured as follows:

const dataset = [
  {'x': '1', 'y': '2', 'z': '3'},
  {'x': '10', 'y': '20', 'z': '30'}
]

I am aiming for the following structure:

const xArray = ['1','10']
     ,yArray = ['2', '20']
     ,zArray = ['3', '30']

This approach was taken:

...
return {
  xArray: _.values(_.mapValues(dataset, 'x'))
  yArray: _.values(_.mapValues(dataset, 'y'))
  zArray: _.values(_.mapValues(dataset, 'z'))
}

While it successfully achieves the desired outcome, there may be room for a cleaner implementation. What would be the most efficient way to group an object by multiple keys?
