Hello,

I'm understating what you mean now. It seems that there isn't this option in the map. I can advise you to get the dataSource into map: $(".selector").igMap("option", "dataSource");. Than find the current point that you need and to update it.

If you have further questions or need further assistance, please feel free to contact us.

I do mean something different.

Suppose I get an initial set of data, say 100 different points. I then get an update to one of those points, I don't know if it was the 3rd or the 5th or the 80th in the original collection. I want to be able to find that point in the maps's data set and update it. I want to avoid having to pass a whole new collection of points over the wire every time just one point needs updating.

In the igGrid, you can "findRecordByKey" or even loop through the rows. I am looking for something similar for the Map.

I hope that makes sense. 

Hello,

You don't need to use igMap for manipulating the dataSource. Every new inserted value in the data will be data.length - 1 position.

You can see this sample of how we bind the real time data to data chart: http://www.igniteui.com/data-chart/binding-real-time-data.

If you mean something different from that what I'm understanding, please send me an isolated working sample with your approach.

I'm looking forward your reply.

I want to initially bind some data to the map, then as more data comes in I want to either add, update, or remove points dependent on the data. It is a web app that displays real time data.
