Hello,

 

In my opinion this is possible using vega / vega-lite 
(https://vega.github.io/vega-lite/) and angularbind capabilities. I let you go  
in Vega / Vega-lite documentation, it has all the facets / repeats features you 
probably want.

 

Here is a basic  example to create a vega chart in Zeppelin:

 

%spark

[ your code to create a dataframe]

z.angularBind(“data”,df.collect)

z.angularBind(“fields”, df.fields)

 

Next paragraph in angular:

 

%angular

 

<script src="https://cdn.jsdelivr.net/npm/vega@5";></script>

<script src="https://cdn.jsdelivr.net/npm/vega-lite@4";></script>

<script src="https://cdn.jsdelivr.net/npm/vega-embed@6";></script>

 

   <div id="vis"></div>

 

    <script type="text/javascript">

    var element = $('#vis');

    var scope = 
angular.element(element.parent('.ng-scope')).scope().compiledScope;

 

      // from here we recover data in the angular scope

    var data = scope.data;

    var fields = scope.fields;

    

 // this step is mandatory to transform the data from angularbind in something 
useable by Vega:    

    var df = scope.data.map(obj => {

        var row = {};

        var i = 0;

        fields.forEach(function(field){

            row[field] = obj.values[i];

            i++

        })

        return(row);

        

    })

 

// and now the chart description part

      var yourVlSpec = {

        $schema: 'https://vega.github.io/schema/vega-lite/v4.0.json',

[your vega-lite specs here]

 

};

vegaEmbed('#vis', yourVlSpec);

    </script>

 

This is just awesome what can be done with Vega  / Vega-lite, it’s a perfect 
companion for Zeppelin when you need more advanced charts in my opinion

I don't know facets, just wondering in what interpreter do you want to use it
