What is a Heatmap?
Wikipedia defines a heat map as a graphical representation of data where the individual values contained in a matrix are represented as colors. In WP Google Maps v6 the colors represent the density of “Markers” on the Map within an area drawn in the Map Editor. Since the radius of the heatmap area is fixed regardless of zoom level, it’s useful for showing a lot of things that gradually separate as you zoom in.
There are many other software that can help you in creating a Google heat map – we strongly recommend to check it out and find the one that suits your needs.
Drawing a Heatmap
Open (or Create) the Map you want to use in the Map Editor (WordPress Dashboard → Maps).
Click the Heatmap tab to open the Google Heatmap Editor.
On the Heatmap Editor page, click the Add a New Dataset button. If you have existing datasets, you can click the Edit button.
- Give your dataset a Name.
- You can choose between the Default Gradient or a Blue Gradient for your Heatmap by clicking the appropriate button. The chosen button will display a border for a few moments.
- You can adjust the Opacity of your Heatmap by entering any value between 0 and 1.0. These numbers represent a percentage between 0 and 100% (.1 is 10%, .2 is 20%, and so on).
- You can also modify the Radius of your Heatmap by entering a new value in the Radius textbox.
When you’ve added all your data Markers to the Map, click the Save Dataset button.

Adding Marker Data without Drawing
If your data composes of geographic coordinates you can simply copy & paste that data into the Heatmap data text box on the Heatmap Editor page. The data must be a series of comma-separated values, for example: (31.038329543616193, -83.63107960671186),(31.03832947179815, -83.63107960671186),(31.545288367366297, -83.01035206764936)
Don’t forget to click the Save Dataset button to save your data.
