This can be done easily. All you have to do is to call the draw() function of the same chart again, with a new data. This will cause the needle to move to the new place.
Notice that if you are using a query to get the data from a remote data source, you can set the query to have a refresh interval and so it will automatically send for a new data and if it was changed, the function that you originally set to be called when the query is back, we be called again.
