Thanks, I will try vega-lite, but I suspect that there may be some issues, because I will be using the output from tensorflow data validation, which produces facets ready data. Not sure why ‘display(HTML(html))’ does not render when using the following import statement from IPython.core.display import display, HTML

I tried - D3.js: probably powerfull, but really complex to deal with as you have to deal with real low level details - Plotly: nice, but I prefer Vega - Vegas (Vega scala API): could be nice but lacks documentation, all Vega-lite is not implemented - Vegalite4s (another scala vega API) : doesn’t work for me - Vega-lite / Vega: just perfect for me for as soon as you understand how to shape your data. Vega-lite is good for a lot of visualizations, and if you want to go to more advanced ones Vega is there. No dependencies on Zeppelin, it’s just Javascript Any feedback from somebody else here?

What kind of errors do you hit ? <stephane.d...@orange.com<mailto:stephane.d...@orange.com>> 于2020年2月10日周一 下午9:20写道： 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 From: Mathieu, Raphael [mailto:raphael.math...@leidos.com<mailto:raphael.math...@leidos.com>] Sent: Monday, February 10, 2020 13:34 To: users@zeppelin.apache.org<mailto:users@zeppelin.apache.org> Subject: RE: EXTERNAL: Re: Work with facets I want to use it in the pyton.ipython interpreter to render interactive html dataset Any ideas ?
