How to Add text to PictureMarkerSymbol in arcgis using javascript

Avishekkumar — Tue, 15 Jul 2014 07:04:11 GMT

I am new to ArcGis, i need complete code of how to add dynamic text on the marker symbol. I have Location Data in Json format....

{locations: [{latitude: 52.1, longitude: 4.1, textToDisplayOnThePictureMarkerSymbol: 34}, {latitude: 52.2, longitude: 4.9, textToDisplayOnThePictureMarkerSymbol: 50}, ...]}

Pls help me...

You need to use a textsymbol

You might want to check out the LabelLayer or, as Jeff Pace suggested, just use a text symbol. Might also be a good idea to check out the nature of infoTemplates; you might end up with a combination of those.

Hi Avishek,

Here is example on how to read a JSON file using the dojo/request/xhr provider. The coordinates and additional attribute information is added to a GraphicsLayer and then labels are generated using the LabelLayer class.

var map, textSymbol, picSymbol;

map = new Map("map", {

basemap: "topo",

var jsonString = { locations: [{ latitude: 51.6220455, longitude: 4.54404212, textToDisplayOnThePictureMarkerSymbol: 34 }, { latitude: 51.8838877, longitude: 4.7527823578, textToDisplayOnThePictureMarkerSymbol: 50 }] };

jsonString = jsonString.locations;

picSymbol = new PictureMarkerSymbol('http://static.arcgis.com/images/Symbols/Shapes/BluePin1LargeB.png', 60, 60);

map.on("load", function (evt) {

for (var i = 0; i < jsonString.length; i++) {

var geometryPoint = new Point(jsonString.longitude, jsonString.latitude, new SpatialReference(4326));

textSymbol = new TextSymbol(jsonString.textToDisplayOnThePictureMarkerSymbol).setOffset(0, -4);

Glad you found the answer. However, crediting yourself with the answer, when others pointed you in the right direction, isnt really great..

Hey Jeff,

Sorry if you get it wrongly. I didn't post this answer and marked as correct ans to get/earn credit. I posted and marked as correct to help others if they are having same requirement, then they can directly get exact answer quickly. Credit goes to ESRI team(specially Nicholas Haney ) they helped me a lot to get this result.

No problem. I understand that. You can mark posts as helpful along the way.

I am ok with marking his response as correct as long as those that contribute to the complete answer get their replies marked as helpful. Now if someone gives a complete answer, their reply should be the one marked correct and not the posters summary. The important thing here is the correct answer being brought to the top more so that a few point being awarded.
