Hi Robert,
Thanks for your interest in Syncfusion products.
Stacked Charts are similar to regular charts except that the Y values stack on top of each other in the specified series order.
FullStacked charts are similar to Stacked Charts except that the cumulative proportion of each stacked element always totals 100%.
I have attached snap shots for Stacked and FullStacked charts

Kindly let me know if you need any more information. Thanks for your patience.
