How to use Data set for the Map element

Hi Everyone,

when I'm using Dataset for displaying markers in  the Map. Markers not coming in the output , but when i manually add the markers then its working.

I have a Table which has 4 columns

Here Maps is the table name.

I have tried placing the map component in detail and summary band, but didnt work while using dataset

could any help me out in displaying markers on map using with Data set.
