In a line chart the single data points surrounded by null points are not rendered.

For ex:
Code:
​
store: { fields: ['billperiod', 'charges', 'adjustments', 'receipts'],
data: [{
billperiod: 'January 2016',
charges: 234243.33,
adjustments: 3423434.12,
receipts: 2342.22
}, {
billperiod: 'February 2016',
charges: 234243.33,
adjustments: 3423434.12,
receipts: 2342.22
}, {
billperiod: 'March 2016',
charges: 234243.33,
receipts: 2342.22
}, {
billperiod: 'April 2016',
charges: 234243.33,
adjustments: 3423434.12,
receipts: 2342.22
}, {
billperiod: 'May 2016',
charges: 234243.33,
receipts: 2342.22
}]
}


In above store the adjustments series misses a data point at billperiod: 'April 2016'. Anyway I can add a point there, I want the line to be discontinuous but a single data point added at that point. I have added a fiddler relating to the same.

Also I have attached the screenshots for expected and currently rendered graph from our production environment.
