ScatterPlotMatrix¶

A scatterplot matrix. This visualization will display a scatterplot for every pair of specified fields, arranged in a grid. Additional fields may determine the size, color, and shape of the points.

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: 10 - d,
      name: d
    });
  }

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

Python

import pycandela

data = [{'a': d, 'b': 10 - d, 'name': d} for d in range(10)]

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

R

library(candela)

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