topic Sum attribute? in ArcGIS Explorer Desktop Questions https://community.esri.com/t5/arcgis-explorer-desktop-questions/sum-attribute/m-p/48855#M289 <HTML><HEAD></HEAD><BODY><SPAN>I just installed ArcGIS Explorer, and I have a question. Is it possible to find all the values of a certain attribute? For example, I am using the National Hydrography Dataset (NHD), and queried for a certain stream. Now I want all the values for length in kilometers for that stream, so I can add them up and find the total length of the stream. I cannot figure out how to do it. Thoughts? Thanks in advance.</SPAN></BODY></HTML> Tue, 17 May 2011 04:17:12 GMT AustinKleinberg 2011-05-17T04:17:12Z Sum attribute? https://community.esri.com/t5/arcgis-explorer-desktop-questions/sum-attribute/m-p/48855#M289 <HTML><HEAD></HEAD><BODY><SPAN>I just installed ArcGIS Explorer, and I have a question.

Some obvious improvements would be:</SPAN><BR /><SPAN>- a more appropriate icon (Sigma?)</SPAN><BR /><SPAN>- using Julian Day Numbers to be able to calculate more than just min and max for date-time fields</SPAN><BR /><SPAN>- a frequency distribution graph as in ArcMap</SPAN><BR /><BR /><SPAN>The C# code is available if you want.</SPAN></BODY></HTML> Mon, 18 Jul 2011 06:07:37 GMT https://community.esri.com/t5/arcgis-explorer-desktop-questions/sum-attribute/m-p/48856#M290 DarrylDempsey 2011-07-18T06:07:37Z Re: Sum attribute? https://community.esri.com/t5/arcgis-explorer-desktop-questions/sum-attribute/m-p/48857#M291 <HTML><HEAD></HEAD><BODY><SPAN>That's great!
