Auto refreshing map widget

[pmishra-4]

Hi,

My thing's property (of location type ) is bind with map . And i am changing it's value through REST api call. How can i refresh location in map widget without loading  whole page.

Hello Prabhat,

You can use Auto Refresh widget and bind it to the service which you are using to assign location to map.

You can configure it in two ways:

1. Refresh location on click

2. Refresh it automatically in some intervals (not recommended in your use case)

I am not able to bind service with auto refresh widget.

[A_Macierzynski]

Auto Refresh widget has it own event called ​Refresh.​ You need to bind it to your service, not service to the widget.

You can bind this event from drop-down hidden menu in the left top corner of every widget (1) or from Auto Refresh properties (2).

Take a look on the biding in the bottom pane also.

Regards,

Adam

Hi Prabhat Mishra, Below procedure is one way of displaying locations of different things at the same time on a map:

• Verify that the Data tab is selected in the upper-right panel and click the Add entity icon.
• Select Thing template.
• Type geti in the Select Service filter.
• Click the Add icon for the GetImplementingThings method.
• Select the MashupLoaded? check box.
• Click the Done button.

• Bind your data property in the mashup to the Google Map widget by dragging and dropping that item onto the map and selecting the data option.

• Change the LocationField to location column in the properties pane of the Google Map widget and choose name in the TooltipField1 as shown below:

• Save and test the mashup.

You can observe that the markers are displayed on selected locations of the things. Also, when you point the mouse on the the location you can observe that the thing name(vehicleID) is displayed on it.

Hope this helps!

Hi Prabhat Mishra,

• In the above example, I have created a Thing template(TestTemplate) with a persistent property(Location).
• Created 4 things(V1Loc, V2Loc, V3Loc, V4Loc) which implements that ThingTemplate (TestTemplate).
• Set the value of this Location property for each of those things.
• Created new mashup and followed the steps mentioned in the previous comment.

This is one way of implementing the scenario. Try this out and please let us know if you have any issues.
