Hi James Athyal
Thanks for your interst in Syncfusion products.
We analyzed your requirement, It is not possible to achieve your requirement using Timeline control, since It is used as a Time Navigator,TimeLineControl gets the data source as the input and return set of datasource within the selected timeline.
Instead, We can achieve your requriment using SyncChartArea, We prepared and attached a SyncChart area sample that matches your requirement.
Please let us know if you have any concerns.
Regards,
Baskaran S
