In this article by Max De Wilde and Ruben Verborgh, the authors of the book Using OpenRefine, we dive deeper into dataset repair, demonstrating some of the more sophisticated data operations OpenRefine has to offer.

The true power of OpenRefine only emerges when you dive into its more advanced features. This article will therefore shed light on the following:
- Recipe 1 – handling multi-valued cells

In this article by Brian Peiris, the author of the book Instant jQuery Flot Visual Data Analysis, we will understand that the axes are the most configurable parts of the chart. Flot gives you the ability to change the position, type, and colors of the axes. It also gives you full control of the ticks and labels on the axes, letting you adjust the number of ticks and alter the formatting. Axes also determine how the data is displayed; you can change the min and max settings to display only a part of the data on the chart and you can also transform the data in various ways.
The full documentation is available at https://github.com/flot/flot/blob/master/API.md#customizing-the-axes. We will take a look at some examples of the configuration options by creating a chart that has a logarithmic axis and another chart that includes multiple axes.Read Working with axes (Should know) in full
