BoxPlot¶

A boxplot. The visualization takes a set of measures (fields) and produces a boxplot of each one. The optional group field will partition the data into groups with matching value and make a boxplot (or set of boxplots) for each group.

This component can be found in the candela/plugins/vega plugin.

Example¶

JavaScript

<body>
<script src="//unpkg.com/candela/dist/candela.min.js"></script>
<script>
  var el = document.createElement('div')
  document.body.appendChild(el);

  var data = [];
  for (var d = 0; d < 10; d += 1) {
    data.push({
      a: d,
      b: d/2 + 7
    });
  }

  var vis = new candela.components.BoxPlot(el, {
    data: data,
    fields: ['a', 'b']
  });
  vis.render();
</script>
</body>

Python

import pycandela

data = [{'a': d, 'b': d/2 + 7} for d in range(10)]

pycandela.components.BoxPlot(data=data, fields=['a', 'b'])

R

library(candela)

candela('BoxPlot', data=mtcars, fields=c('mpg', 'wt', 'disp'))
