PRE-REQUISITES

INSTALLATION INSTRUCTIONS

  1. Download the latest release
  2. Install the plugin to your application - region_type_plugin_com_jk64_heatmap.sql
  3. Supply your Google API Key (Component Settings)
  4. Add a region to the page, select type GeoHeatmap [Plug-In]
  5. For SQL Source, enter a query with 3 columns (see example below)
  6. Update the Number of Rows to a reasonable upper limit (default is 15, you probably want a much bigger number)

Sample query

select lat, lng, weight from mydata

If you don't have any "weight" to go with the data points (e.g. population, earthquake magnitude, sales volume), just set the third column to 1, e.g. select lat, lng, 1 from mydata.
