Can somebody help me understand how to use the classBreaks function under esri/renderers/smartMapping/statistics in JS API 4.5? The documentation gives an example but I cannot figure out how to feed the results into the classBreaksRenderer. I've pasted my JS code below that contains a modification of the code example plus my attempt to feed the output from classBreaks into a renderer. I know it's wrong but I'm not clear how to fix it. Any help would be appreciated. require([
'dojo/dom',
'dojo/number',
'dojo/on',
'esri/Map',
'esri/views/MapView',
'esri/layers/FeatureLayer',
'esri/renderers/smartMapping/statistics/classBreaks',
'dojo/domReady!'
], function(dom, number, on, Map, MapView, FeatureLayer, classBreaks) {
// Create the Map element
var map = new Map({
basemap: 'oceans'
});
var viewProperties = {
center: [-77.3936, 35.1377],
zoom: 8
};
// Create the MapView element that will hold the map
var view = new MapView({
container: "viewDiv",
map: map
});
view.center = viewProperties.center;
view.zoom = viewProperties.zoom;
var renderer = {
type: 'class-breaks',
field: 'Alligator'
};
renderer.addClassBreakInfo(breakInfos);
function genClassBreaks () {
classBreaks({
layer: featureLayer,
field: "Alligator",
classificationMethod: "quantile",
numClasses: 4
}).then(function(response){
var breakInfos = response.classBreakInfos;
});
}
var featureLayer = new FeatureLayer({
url: "https://services.arcgis.com/ycIuRaoIC4UuCDAS/arcgis/rest/services/Alligator%20Sightings%20by%20County%20in%20NCSU%20Survey/FeatureServer/0",
renderer: renderer,
outFields: ["*"],
definitionExpression: "Alligator > 0"
});
// Add featureLayer to the map
map.add(featureLayer);
});

I'm stuck on another aspect of this same script (pasted below). I have simply switched the initial layer above from States (3) to Counties (2). In doing so, the application does not render the Counties layer properly. I've determined that the code in the detailsTask_getAllDetailsCompleteHandler function is setting layerMapSource to the last layer in the ArcGISDynamicMapServiceLayer. In this case, that's States. Once I change the layer in the dropdown, it renders both States and Counties properly. But I cannot figure out how to get the code to properly render the Counties layer if it is the first one to display.

I have a simple application where I'm generating a 5-class choropleth map using one of the ESRI demographic datasets. I want to be able to dynamically switch between different layers (i.e., states or counties) by only displaying one at a time. I'm able to render the quantiles on the initial layer (states), but when I switch to counties I can't figure out how to change the GenerateRendererTask to render the counties. I plan on implementing this code in an application with many more layers than just two, so I don't want to go about hard-coding in the switch like I've done in the layer_changeHandler function. So in addition to the help with rendering, can someone help me with a more elegant way to do that switch? Code:

I'm working on a widget for the Viewer for Flex. There are some elements that I disable based on certain conditions, such as the layer that is loaded or a variable that is selected. For example, I have a CheckBox that when clicked will convert a variable to a density (e.g., pop per square mile), and I disable it (enabled = false) when a rate variable is displayed. When I disable the CheckBox, I also convert the Spark Label next to it to italics and change the color to a medium gray to indicate that it is inactive. My problem arises when I want to return the Label text to the normal style and the default color (see line 17 below). In the development environment, the widget is gray and the text is white. I have hard-coded this color change, but when I move this widget over to another application that uses a different color scheme with black text, then the Label suddenly stands out wrong because I'm coloring it white. What I really want to do is to read the text color that is specified in the main config.xml file for the viewer application and assign that color in line 17. How do I read that from inside a widget?
protected function classificationFieldsDDL_changeHandler(event:IndexChangeEvent):void

classificationField = DropDownList(event.currentTarget).selectedItem.data;

if (classificationFieldNormalize == '0')
{
normalizationChkBx.selected = false;
normalizationChkBx.enabled = false;
normalizationLabel.setStyle('fontStyle', 'italic');
normalizationLabel.setStyle('color', '0xa0a0a0');
}
else
{
normalizationChkBx.enabled = true;
normalizationLabel.setStyle('fontStyle', 'normal');
normalizationLabel.setStyle('color', '0xffffff');
}

I'm making some modifications to the Thematic Widget (http://www.arcgis.com/home/item.html?id=ced1ad5fe30f4304adb056cdcbdc9ad0) for our site, and I've been asked to include counts of features in the legend. Has anyone done this before? I'm still relatively new to the Flex API, so I'm not sure where to look to find any methods that will calculate counts of features in categories generated with a classification renderer on a dynamic layer. It would obviously need to update the counts when the classification type switches from Quantile to Equal Interval to Natural Breaks, etc.

Here's the config file. I checked it again and verified that closing the Swipe Spotlight Widget makes the dynamic layers disappear. I believe they are simply ordered below the gray canvas.

I discovered the source of the problem, but not the solution. When I click the dropdown menus for Top Layer and Bottom Layer, my default basemap (Light Gray Canvas) is listed at the top, above all of my operational layers. So when I close the widget, it reorders that basemap on top of all other layers. All other basemaps appear at the bottom of those two dropdown menus, so if I change the basemap my operational layers show up again. I tried moving my <basemaps> section of code below my <operationallayers> section but that didn't make any difference. Any thoughts on this?

I'm testing out the Swipe Spotlight Widget in App Builder 3.6. It works incredibly well, but when I close it my top layer disappears. It's almost as if it's setting the transparency to 100%, because my popups still work. Any idea why this is happening?

I have a feature class of roads, and each feature has separate elevation values (Z) for the nodes. I would like to display this data three-dimensionally, but using both Z values so roads that have one end higher than the other appear to slope. I cannot find any tools anywhere that will let me use more than one Z value for vector features. Does anyone have any idea how this can be done?

I have an application where I need to calculate several different possible routes between origin and destination points on a road network. The best option that I can come up with at this time is what is commonly called the kth best route, which would return the shortest route, the second shortest, third shortest, etc. I've searched around on the web for a solution to this and have come up empty. Does anyone have any experience with this, or do you know if it is possible to extract this information out of Network Analyst? Any help you can provide would be most appreciated. Brian Frizzelle
