Hey Raúl Jiménez Ortega‌! I have no idea how internal changes in 4.9 could be affecting a custom stream service that delivers the same old Esri JSON features, but it definitely looks like you're on to something. hopefully the folks from the JSAPI team can help out. in the meantime, is your prototype something you can push up on GitHub with instructions to get it up and running? cc/ Bjorn Svensson‌ ...

in esri leaflet we're not doing anything special. we just pass through whatever JSON you supply. if this thread isn't helpful, I'd recommend figuring out the appropriate syntax for your raster function directly at the REST endpoint and asking for help from image service experts if necessary. https://gis.arkansas.gov/arcgis/rest/services/ImageServices/DEM_1M_2018/ImageServer/exportImage  ...

i don't know anything about rotating labels, but i was definitely able to display and customize the X and Y axis labels in the ember-cli-cedar playground. { "type": "bar", "datasets": [ { "url": "https://services.arcgis.com/uDTUpUPbk8X8mXwl/arcgis/rest/services/Public_Schools_in_Onondaga_County/FeatureServer/0", "name": "Number_of_SUM", "query": { "orderByFields": "Number_of_SUM DESC", "groupByFieldsForStatistics": "Type", "outStatistics": [ { "statisticType": "sum", "onStatisticField": "Number_of", "outStatisticFieldName": "Number_of_SUM" } ] } } ], "series": [ { "category": { "field": "Type", "label": "custom" }, "value": { "field": "Number_of_SUM", "label": "also custom" }, "source": "Number_of_SUM" } ] }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

yup. you can configure GP services to output all sorts of different results. ... View more

there's no need to guess. inspect the url and the request parameters for a successful request when visiting the raw service endpoint and compare and contrast that with what's being sent from your esri-leaflet app. ... View more

i meant open the developer tools in your browser and inspect the individual requests and responses. ... View more

try snooping the web traffic to see the actual request and response. ... View more

you need to call Geoprocessing() from within your `addMarker()` function. bonus points if you start passing through the latitude and longitude as arguments instead of relying on a global variable. ex: Geoprocessing(e.latlng.lng, e.latlng.lat)‍‍ // ... function Geoprocessing(long, lat) { })‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

> However I cannot get the two to talk to each other. are you saying you can't get your webpage to talk to ArcMap? or are you saying you can't figure out how to invoke the GP service using the coordinates that the user drew in the esri-leaflet app? ... View more

this is switching gears completely, but you can find a JSAPI example that uses chart.js using an array of 'raw' values instead of features here: Query statistics client-side | ArcGIS API for JavaScript 4.9 > Is there a way I can directly send the extracted data back to the webpage? if your GP service generates a list of values instead of features you can access them in a callback using esri-leaflet-gp and then wire up a chart of your own. there are lots of charting libs out there. the crux for you will be to adapt the response to match the data model the one you choose expects.  ...

you can find a few live examples that use esri-leaflet-gp to execute gp tasks and display the results in leaflet here: https://github.com/jgravois/esri-leaflet-gp#demos  ... View more

very cool use of Esri Leaflet! ... View more

I reproed the error you're reporting in ArcGIS Pro 2.2.2 and forwarded on the report to the appropriate team. Sorry for the inconvenience. Create a wkid:3857 feature class and add a few points to it. Open the ‘Features to JSON’ tool. Check the ‘Output to GeoJSON’ and ‘Project to WGS_1984’. Inspect the output file in a text editor. The CRS is labeled as “EPSG:4326” but the coordinates are still northings and eastings. ... View more

Thanks Y'all! Hope you had half as much fun as we did! ... View more
