Hello marchip,
If you set the value to null, it will have no graphical representation, e.g.:
var sampleData = [ { Day: 'Monday', Keith: 30, Erica: 15, George: 25 }, { Day: 'Tuesday', Keith: 25, Erica: null, George: 30 }, { Day: 'Wednesday', Keith: 30, Erica: 20, George: 25 }, { Day: 'Thursday', Keith: 35, Erica: 25, George: 45 }, { Day: 'Friday', Keith: 20, Erica: 20, George: 25 }, { Day: 'Saturday', Keith: 30, Erica: 20, George: 30 }, { Day: 'Sunday', Keith: 60, Erica: 45, George: 90 } ];
Best Regards,
