Hi James,
Thanks for your interest in Syncfusion products.
We can display a dot for a value between two empty by Setting EnableEffect property to true.
Code Snippet:
[XAML]
EnableEffects="True"
ShowEmptyPoints="False" />
We have also prepared a sample based on your requirement. Please find the sample from the attachment.
Please let us know if you need any further assistance.
Regards,
