Happy Monday! Anyone can give me some suggestions on this? Let's say I start from this example: http://developers.arcgis.com/javascript/samples/renderer_color_ramp/ What I need to do is to allow a user to manually pick some counties and export name for the selected ones. Would someone give me some examples or pointers? Thanks a lot!

Since you don't need a proxy, try to remove below codes: urlUtils.addProxyRule({ proxyUrl: "/proxy", urlPrefix: "test25.net" }); I don't have any proxy setup, I just replaced the url in the proxy with my address and hoped it would work! Is there a way to make it run without the proxy?

Thanks again for your reply. This is not doable in my case as the source of csv is a dynamic web service that generates csv file. We will plot up to 1000 points and provide a way for end user to download the 'original' csv data. dawen, you might consider publishing the data as an ArcGIS Online hosted feature service and updating the maxRecordCount property of the service itself. http://forums.arcgis.com/threads/94744-Is-it-possible-to-change-the-Max-Record-Count-on-an-AGOL-hosted-Feature-service

Thanks for your reply John! I understand 1000 is a big number, if I have to change it to 1500 or so, can you tell me how to set it if the source is a csv file, there's not ArcGIS Server involved in this case. In my case, I display csv.graphics.length and the max value I see is 1000. Dawen Dawen, because we have no concept of readonly properties in JavaScript, maxRecordCount is a property of a FeatureLayer that is technically writable, but is really only intended to learn what value has been set by ArcGIS Server when interacting with a particular service. in general, the same concepts for all other graphicsLayers is relevant to a CSV layer. its usually not an optimal user experience to have people interacting with more than 1,000 individual features.

I really like the CSVLayer in version 3.9 of the API! What I want to do is simple: display the points in a CSV file. I run into problem when there are more than 1000 points. I have been trying to set maxRecordCount when I create the CSVLayer (see below), but it still renders 1000 points. Any help? Thanks! csv = new CSVLayer("./demo.csv", { id: "locations_in_bbox", maxRecordCount: 3000 });

I'm trying to access a sample "renderer using a function (county population)", the link from the search result is copied below, but it's not valid any more. https://developers.arcgis.com/javascript/jssamples/renderer_feature_layer_function_animate.html

Since I got a few inquiries on this, it would be helpful to post it here. The trick is to load the cx_Oracle.pyd (from a Windows 7 64-bit machine) and 64-bit Windows Oracle Instant Client's .dll files into a specific folder on the Linux server. It should be the site-packages directory of python27, something like: /data/ags/arcgis/server/framework/runtime/.wine/drive_c/Python27/ArcGISx6410.1/Lib/site-packages Below are the files I copied: [SNIPPED] -rw-r--r-- 1 root root 134144 2012-09-13 15:57 cx_Oracle.pyd -rw-r--r-- 1 root root 357888 2012-09-26 18:10 orasql11.dll -rw-r--r-- 1 root root 140233216 2012-09-26 18:10 oraociei11.dll -rw-r--r-- 1 root root 1235456 2012-09-26 18:10 oraocci11.dll -rw-r--r-- 1 root root 1600000 2012-09-26 18:10 orannzsbb11.dll -rw-r--r-- 1 root root 481792 2012-09-26 18:10 ociw32.dll -rw-r--r-- 1 root root 137728 2012-09-26 18:10 ocijdbc11.dll -rw-r--r-- 1 root root 683008 2012-09-26 18:10 oci.dll Forgot to provide a followup on this: we got a solution after working with ESRI support for more than a week. I can provide more details if someone runs into the same issue. Contact me through message. Two software enhancement requests were logged that related to this: [#NIM085268 Enhance ArcGIS server 10.1 for Linux to better handle GP service based on python script that involves custom modules and database connection client ] [#NIM085267 Enhancement request: Put Linux based Python with ArcGIS server 10.1 on Linux. ]

Thanks Derek, but this is not exactly what I'm looking for. What I can remember is that on that page, maybe referenced from the link I provided, there are examples on different picture symbols and we could get the URL information. For example, I have below codes to represent a work location and I got the URL from that page. workSymbol = new esri.symbol.PictureMarkerSymbol({"angle":0,"xoffset":0,"yoffset":0,"type":"esriPMS","url":"http://static.arcgis.com/images/Symbols/PeoplePlaces/Office.png","contentType":"image/png","width":18,"height":18}); Same content is now here: http://developers.arcgis.com/en/javascript/jshelp/inside_renderers.html

‎04-18-2013

Can you help me find this as well? There used to be a page for looking up different symbols, epecially the PictureMarkerSymbol. But I cannot find it any more. The URL in my bookmark is: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp_start.htm#jshelp/inside_renderers.htm A number of things have moved, but all content is still available. Anything specific you're looking for that I can help you find?

Thanks for your quick response Derek! The data I have is a person's synthetic activities. Here the person could be in U.S., or other countries and the extent for their activities could be small (and the extent is small) or relatively big. Do you have suggestion on how to set the intial extent when I have all the data ready? Or, just ask my end-users to wait till ESRI provides better basemap for some regions? 🙂 Unfortunately no, there's not a way to know whether tiles displayed from a basemap are actual map tiles or "map unavailable" tiles.

Just a quick note: as long as the data is prepared in the way the clusterLayer class expects, it can be from any source. This is the type of thing that's easy to test and figure out on your own :). The answer is yes, you can query against a layer in map service. I used a feature service because it was readily available.

I need to show a set of points on a basemap, e.g., ESRI's streets map. I use esri.graphicsExtent(graphics) to set the default extent. The problem here is that on some regions, the basemap is not available for a given extent. Altough the user can zoom out to see the points, it would be nice if I can set the default extent in a better way. The question is: for a given extent, is there a way to check whether the basemap is available?

Some more details. I have other layers in the application and they are typical feature layers returned from a GIS server. What I want to accomplish is to have a link on the popup to retrieve dynamic information for each layer. For a feature layer, I can use map.infoWindow.getSelectedFeature() and then query the attributes to get the ID I need. But I have trouble in doing this for a GraphicsLayer as map.infoWindow.getSelectedFeature() returns null . I have some point data in csv format with x, y and list of attributes and I use a GraphicsLayer to plot them on a basemap. (Similar to ESRI's example on "Map with CSV data", http://help.arcgis.com/en/webapi/javascript/arcgis/jssamples/ags_MapwithTable.html ) A popup window is added when a point is clicked. Things work fine until I need to create a dynamic link on the popup window to retrieve more data: here I need to use a field, e.g., ID, in the attributes. Below is a walk-around I'm using which I don't like and I'm wondering what's right way to handle it. Thanks in advance for any suggestion you might provide. var rawAttrList = globals.map.infoWindow._contentPane.innerHTML.split("<br>"); for (var i = 0; i < rawAttrList.length; i++) { if (rawAttrList.split(" = ")[0] == "ID") { ID = rawAttrList.split(" = ")[1]; } }
