boxplot with jittering

[BeWu]

Hi, 

I have a boxplot created using visual "Box and Whisker by MAQ Software". 

Is it possible to add jittering to the boxplot? When I create a measure 

Jitter = 0 - (RAND() - 0.2) it is not possible to add it into Axis category. Any ideas how to solve this problem ? (greenish points represent number of people entering rooms montly, each point = room). Thanks for help and suggestions.

Here's an example of one way to do it, with the Deneb visual.

  "data": {"name": "dataset"},

  },
  "spec": {
    "transform": [
      {
        "calculate": "random()-0.5",
        "as": "jitter"
      }

        "encoding": {
          "y": {

            "type": "quantitative"
          }
        }
      }
    ]
  }
}
