Variable width bar chart using JavaScript

A report shows Unit cost and Unit price of all products. It also works out the Profit Margin from these two.

Business owners are naturally more interested in products with a high profit margin as well as a high unit price.

In this recipe, we will create 'Variable width bar chart' using JavaScript, which shows a bar for every product. The length of bar will indicate the Profit Margin, whereas width will indicate the unit price.

Getting ready

Create a simple list report with Product name, Unit cost, and Unit price as columns.

Also add a calculated item, called Margin, to the list to compute the Profit Margin and define it as: ([Unit price]-[Unit cost])/[Unit cost].

How to do it...

Drag a new HTML item on the list ...
