James, There is no configuration option, but you can modify the code in the Widget.html. Line 35 in the latest version would add "checked" after the type="checkbox". 34: <div style="margin-bottom:7px;"> 35: <input data-dojo-attach-point="showTotals" type="checkbox" checked /> 36: <label data-dojo-attach-point="showTotalsLabel">${nls.showTotals}</label> 37: </div> Regards, Tom

Chelsea, I have added my vote! Regards, Tom

Chelsea, They are still in composite hierarchy order, not score order. It would be nice if there were a REST service option for setting the order as needed. Regards, Tom

Greetings, I ended up contacting support to see why this wasn't possible. The answer was that this was by design. The renderer for a heatmap requires a schema for possible weighting fields and uses the geometry type as set in a featurelayer. Support was also adding a documentation enhancement that would better describe that the renderer should be used with a featurelayer. I did find that you can use a unique value renderer with a graphicslayer, so this does seem a bit inconsistent. It would be nice to render a heatmap in a graphicslayer just based on the geometry and without the ability to use a weight field. I am going to work on moving my table data into a feature collection that can be used with a featurelayer so it can render a heatmap. Support pointed me to an example that will be helpful.

Greetings, I have created an app that we use for public safety public disclosure requests. The app uses a geoprocessing script that queries a database (not geodatabase) that returns rows that have lat/lon coordinates. Points are then created with the attributes and added to a GraphicsLayer and drawing the layer with a SimpleRenderer to begin with. I have added a couple of buttons that allow the user to change how the points are displayed. This displays fine with a SimpleRenderer or UniqueValueRenderer, but won't work with a HeatmapRenderer. There are no errors in the console, just a blank map. I have read the documentation and there isn't anything that says a HeatmapRenderer won't work with GraphicsLayer. I have seen some similar posts that don't actually answer this question. The code for this seems pretty straightforward. Here are some snippets for changing the renderers: function displayBasicPoints() { var marker = new SimpleMarkerSymbol(); marker.setColor(new Color([168, 0, 0, 0.25])); var resultsRenderer = new SimpleRenderer(marker); resultsLayer.setRenderer(resultsRenderer); resultsLayer.refresh(); } function displayHeatmap() { resultsLayer.spatialReference = map.spatialReference; var hr = new HeatmapRenderer(); resultsLayer.setRenderer(hr); resultsLayer.refresh(); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ You can also view the app at: DEX Queries Thanks very much for any help!

Measure Widget Users! I have posted an update that fixes a problem with editing measures. The widget was using a couple of event listeners, but recently one was being ignored. This has been fixed and the widget is functioning properly now.

Jacqueline, Thanks very much! You can override the default value by adding 2 lines of below line 124 in the measure Widget.js. It will look like this: this.textSymChooser.textPreview.innerHTML = "Sample Text"; // line 124 this.textSymChooser.textFontSize.value = 12; this.textSymChooser.textFontSize.textbox.value = "12"; Regards, Tom

Greg, Sorry for the late reply. I am on the road today and have limited access to the internet. I would set a breakpoint on the last line and then you can examine the values for both the pl and newPL variables. The code looks correct, the pl variable may not have a value set.

Greg, Probably the simplest solution would be to reverse the order of the path points in the polyline used. I have updated my example to show how to do this. Here is a function that will reverse the path order: function reversePolylineOrder() { var newPL = new Polyline(map.spatialReference); var newPath = []; for (var i = pl.paths[0].length - 1; i >= 0; i--) { newPath.push(pl.getPoint(0, i)); } newPL.addPath(newPath); pl = newPL; }‍‍‍‍‍‍‍‍‍ Regards, Tom

Brian, I have the same problem. I have discovered that popup configuration is disabled for all layers if you try and edit just one layer that doesn't have the shape field at the bottom. I was happily configuring popups for several layers and stumbled on one layer that didn't have the shape field at the bottom. At that point I couldn't configure any popups in my webmap whether the shape field was at the bottom or not. I could save my webmap, do a hard refresh with cache flush and then I could configure popups again. Not the most elegant way to get through many layers to configure popups. Regards, Tom

André, Are you wanting to highlight the selected features on the map? You can easily highlight them by setting a selection symbol. Here is the documentation that might help with that: FeatureLayer | API Reference | ArcGIS API for JavaScript 3.19 Regards, Tom

Jason, Thanks for the code, that gives me some context. Maybe try: tiff = r'C:\Temp\my_tif.tif' png = r'in_memory\my_png.png' CopyRaster_management(tiff, png, pixel_type='32_BIT_SIGNED', format='PNG') b64 = base64.b64encode(png.read()) Regards, Tom

Jason, It should already be open, I was suggesting that you read it. Could you provide the code you have attempted? Regards, Tom

‎02-24-2017

Jason, I had done something similar, but was loading an image file from disk. To encode it I had to read it. Something like: with open(driverPhoto, "rb") as imageFile: encodedPhoto = base64.b64encode(imageFile.read()) Perhaps you have to do a read as well. Regards, Tom

Andre, Looking at your query, it looks like you are trying to do a wildcard selection of a date field. Please try using a more specific selection like: query.where = "nud = '" + userVal + "'"; Date fields can be a bit tricky to work with as they may contain date/time values so finding an exact match would mean also have to specify a time or time range. Something like: query.where = "nud between '" + userVal + " 00:00' and '" + userVal + " 23:59'"; Regards, Tom
