Heat Map Graph lets administrators build data heat maps backed by SQL SELECT queries on WordPress tables. Configure:
<ul>
<li>Query: a single SELECT statement targeting WP tables</li>
<li>Field mapping: row, column, and value fields produced by the query</li>
<li>Color range: hex colors for min and max</li>
<li>Status: enable/disable</li>
</ul>
Use the shortcode on pages/posts:
<pre><code>[heat_map_graph id="123"]
</code></pre>
Security features: 
– Validates SQL is a single SELECT against WP tables only 
– Blocks DML/DDL keywords 
– No multiple statements 
– Admin-only UI with nonces and strict sanitization
On activation, two sample heat maps are created: 
– Posts per Day per Category (Last 30 Days) 
– Number of Post Tags per Category

Heat Map Graph

Create and display heat maps from custom SQL queries. Define row, column, and value fields, select color ranges, and render via shortcode.

This plugin allows you to create a heatmap based on mouse clicks and cursor movements. By default, positions of the cursor in the work area (e.g. main page of the blog, any post, categories, tags, etc.) will be saved per some interval in seconds (5 seconds by default) for every user that will visit your homepage.
Also, you can add click tracking and the position of every mouse click will be saved too. All the saved coordinates will be saved in the database and can be rendered by admins at any time with the “Display Heatmap” button on the main page.
Major features of the plugin 
– Automatically saves the position of the cursor per some time interval for every user 
– Immediately saves click positions on any page 
– Allows to set own position-save interval 
– Saves everything in your own WP database. No 3rd party services involved!
