I know this must be possible just looking for a tutorial or video showing how. I have a shapefile with points representing housing sale prices across a neighbourhood and I'm looking to create a heat map or gradient across the whole neighbourhood showing higher and lower prices in different areas. Any ideas how to accomplish this?
do you have the Spatial Analyst or Statistical Analyst or 3D Analyst extensions? And what version of ArcMap... assuming yu are using it and not another platform
Woops, I'm using ArcMap 10.1 and I have access to all the extensions available, including those you mentioned.
Google and You Tube Associate ... will help, but I find the video stuff I presume, but it is also useful to see the old school static lesson plans in the help files. for example
Go to the main Extensions link...
An overview of the extensions of ArcGIS—Help | ArcGIS for Desktop
pick and extension and see if they have a tutorial or lesson plan ... ie
Introduction to the ArcGIS Geostatistical Analyst Tutorial—Help | ArcGIS for Desktop
Or sometimes they have buzz words like "visualize" etc like in this which will give you the key

beause things like heat map are not a new invention, just a new term just a catchier term than applications of choropleth maps I supposed Heat map - Wikipedia, the free encyclopedia
so your best bet is to check the demos with esri where they are advertising "visualization" "display your data" and "analyse your data" to get the visual key to what you want.
