I think you can only set offset for Point geometries by means of the graphic object definition. For the Polyline graphic you could iterate through the line path and specify an offset for each coordinate: var g = routeLayer.graphics[1];  // red line var offset = 0.0001;  // decimal degrees for (p in g.geometry.paths){   var path = g.geometry.paths ;   for (pnt in path){     var xy = path[pnt];     xy[0] += offset;     xy[1] += offset;   } } routeLayer.redraw(); ...

Yes that should work for 4.0.  The pixel value is returned as field "Pixel Value". ... View more

If the graphic is not in the eventsLayer, then the remove function won't work. You can try: view.graphics.remove(view.popup.selectedFeature); or view.graphics.removeAll(); If you provide more code someone might be able to help. ... View more

I would think it refreshes automatically after something like: graphicsLayer.remove(graphicsLayer.graphics.items ) ... View more

Yes in that case a mosaic published as an Image Service is the only option if you want to apply raster functions. ... View more

Too bad   I'm not sure what your requirements are, but you can publish rasters from inside a MXD as a standard Map Service and use it in the view as a MapImageLayer [MapImageLayer | API Reference | ArcGIS API for JavaScript 4.0].  Then use an IdentifyTask [IdentifyTask | API Reference | ArcGIS API for JavaScript 4.0 ] to get the raster values. ...

There are a couple things about your Image Service that's bothering me. 1) Fields: None 2) Max Mosaic Image Count: null 3) Supports Statistics - option not available ... View more

One more thing, have you calculated statistics on your rasters in the Image Service? ... View more

Not sure if that could be a limitation.  According to the documentation here (ArcGIS Help 10.1 ) the Pixels capabilities "Allows developers access to the pixel blocks of individual rasters in a mosaic dataset" and should be available in 10.1. ... View more

Have you enabled "Pixels" in you Image Service capabilities? ... View more

Try creating an in-memory Layer file while iterating and working with that instead: # list lyr files in workspace lyrs = arcpy.ListFiles("*.lyr") for l in lyrs:   lyr = arcpy.mapping.Layer(arcpy.Describe(l).catalogPath)   layers = arcpy.mapping.ListLayers(lyr)   for layer in layers:     # process layer ...

Now I don't understand what you are trying to do   Your original question stated you want a color ramp, but in your code you are applying a fill symbol.  Please read the documentation on the ClassBreakRenderer first and play around with it.  Tip: don't run the jQuery $(document).ready within the require function.  You can create the layer listener functions right after you have initialised the layer.  I would also be careful of building code around dynamically created DOM elements like the graphics layer.  You have set the renderer for the layer already and don't need to wait for the document load to run it again. ...
