This is an example of a colorful stacked bar chart made with the WP Business Intelligence plugin. The chart above is displayed using data from a secondary MySQL database, that is a db that is not part of the WordPress install. The SQL query used to generate this chart can be seen below. It is a ficticious record of stock prices for three major tech companies between dates in January and June of 2017.
You can easily add a chart like this stacked bar chart to your own website using our plugin WP Business Intelligence Pro which comes with more beautiful charts and features.
