Sparklines in Jupyter notebooks / ipython and Pandas

Sparklines in Jupyter notebooks / ipython and Pandas

Hugos mostly inane waffle about tech and coding

For those who are unaware sparklines are very small charts which are typically rendering inline with data. These are effectively condensed charts which give visual clues to the reader. They grew in prominense after being advocated by Edward Tufte one of the grandfathers of data visualisation.

In a previous post we examined how to create sparklines in Excel when a library does not natively support them. For the curious this used a trick with a formula and a special font, details of which are documented here.

Whilst this is a good approach for creating static reports a great deal of interactive data analysis will be done using python and pandas.

Many data scientists will choose to use Jupyter notebooks or ipython as a smart interactive shell, so lets look at how we can add sparklines to Jupyter / pandas.

Lets get started. We will need a few imports and…

Having just received a rejection from my only pending CFP submission, 2019 will likely be the first year since 2013 where I don’t give a conference presentation.

It’s always disappointing when the effort of crafting a talk in response to a CFP doesn’t result in the opportunity to give the talk, but my strike rate over the last few years has been pretty good and I’m grateful for the awesome opportunities I’ve been afforded by events in New Zealand, Sweden, Estonia, Vietnam, US and Australia.

As anyone who’s prepared and given a conference talk will know, there’s a lot of time and effort involved – from crafting a CFP submission, to refining the story, building a slide deck, performing some practice runs, travelling to the event (especially from somewhere as a remote as Australia!), and actually delivering the talk. In the absence of this work, I’m looking forward to putting more…

A SMART approach to your employees’ New Year’s resolutions — or any time

Health Care Conversation
A forum for fresh perspectives and discussion – all in the name of health care

It’s that time of year again. With the holidays close by, it’s natural for your employees to start thinking about New Year’s resolutions. Keeping a promise to oneself is more easily said than done, though. Year after year, people enter January with ambitious goals: losing weight, exercising more, signing up for a race. Sound familiar? So what actually goes wrong with all this positive intent?

According to the American Psychological Association, the way we define our resolutions can foreshadow how successful we will be in keeping them. “By making your resolutions realistic, there is a greater chance that you will keep them throughout the year.”1

The Centers for Disease Control and Prevention (CDC) offers a great way for employees to set themselves up for success. Use your internal communications channels to educate employees on setting goals by making SMART resolutions.2 Goals should be specific, measurable, attainable, realistic and…
