I am a neophyte to GIS. I have historical data for all of my ambulance calls for the past year with attributes including day of week and time of day. Using Arc Desktop Explorer I was able to import the x- and y-coodinates to display the point data for say the 6pm hour on a Thursday. I am now using ArcMap and would like to now be able to display the data as what I refer to as "hotspots" or density mapping. I'm not sure if that is the correct terminology. What I mean by that is an area would display darker in color in areas where the number of ambulance calls are greater in number. I'd also like to be able to select different hours in my query and have the hotspot map update as the query changes. I'm sure this is possible, I'm looking for someone to please point me in the right direction. Thank you for your time and anticipated assistance. Thank you!
