I have a point dataset wih 911 calls for one year, including a column with the date (day) when the call was made.

I would like to create a graphic that shows in which month how many calls were made, to analyze the temporal variation. I add a picture to illustrate the way the result should look like.

enter image description here

Can this be done in ArcGIS and if yes how? How do the data have to be prepared, is it necessary to add a column indicating the month and can this be done automated (as there are a lot of features present)?

Yes, this can be done in ArcGIS. The following is the link to the top of the graph section on online ArcGIS 10.2 help. http://resources.arcgis.com/en/help/main/10.2/#/What_are_graphs_in_ArcGIS/003300000001000000/ If you are using a different version of ArcGIS, you can simply replace the 10.2 in the URL with your version (that usually works).

  • How do I have to prepare the data? I have the Point Feature class, each Feature indicating one occurence of the phenomenon and a date column. I already made a month column in order that the number of Features per month can be displayed, but how? – the_chimp Apr 6 '16 at 4:16
  • You need to give it a try and post another question with your results, showing where you are stuck. – RHB Apr 6 '16 at 15:50
