Current behavior Hi I have this as data in a pie chart : { ‘name’: ‘Carburant Pétrolier VE’, ‘value’: 2306.18, ‘filter’: ‘G33’ }, { ‘name’: ‘Assurance (Prime et Fond de garantie)’, ‘value’: 1537.95, ‘filter’: ‘G69’ }

and on select when i get the data selected it returns only name and value NOT filter, is there a way to get the filter.

Expected behavior I should get name and value and filter

Reproduction of the problem

What is the motivation / use case for changing the behavior?

I was thinking about putting all extra data that we want to pass in click/tooltip events in a separate property. So the data would look like this:

{
  'name': 'Carburant Pétrolier VE',
  'value': 2306.18,
  'data' : {
    'filter': 'G33'
  },
  ...
},
{
  'name': 'Assurance (Prime et Fond de garantie)',
  'value': 1537.95,
  'data' : {
    'filter': 'G33'
  },
  ...
}

This way, everything you would like to pass in those events (in addition to the name and value properties) should be put under data. Does that make sense?

Update 19 August 2019

This feature has been implemented and available since version 12.0.0. Instead of data, the property is called extra The format now looks like this:

{
  'name': 'Assurance (Prime et Fond de garantie)',
  'value': 1537.95,
  'extra' : {
    'filter': 'G33'
  }
}
