Joyful or informative charts? Best practices in visual analytics

Small_packed_bubble_chartStephen Few, noted visual analytics expert and the original inspiration for our work in the field, recently wrote about criticisms of best data visualizations practices. In particular, Amanda Cox of the New York Times said, “There’s a strand of the data viz world that argues that everything could be a bar chart. That’s possibly true but also possibly a world without joy.” And Nathan Yau of Flowing Data wrote, “in visualization you eventually learn that there’s more to the process than efficient graphical perception and avoidance of all things round. Design matters, no doubt, but your understanding of the data matters much more.” These are both people who have a body of work that I admire but I am also surprised at these comments.

This discussion reminds me of a similar problem in marketing and web analytics. Generating traffic that leads to sales is good. Eventually, someone finds a way to generate traffic that leads to not many new sales, but management is misled to think this must be good since traffic leads to sales. This is similar to “look, this chart is beautiful“, but hard to interpret or understand. So, while we delivered fun graphs, minimal information is shared. This may be good for traffic, but not so much for higher sales.

I suspect that part of this recent criticism can be traced back to Stephen’s recent criticism of Tableau, “Tableau Veers from the Path“. In it, he mentions a new graph type in Tableau, packed bubble charts and contrasts them with bar charts. This is an example of the “avoidance of all things circular”. Is Stephen truly anti-joy@f16 Will an example show him to be wrong@f17 Let’s give it a try and you can judge for yourself.

Here’s a packed bubble chart example Continue reading

Avoid flatline charts—visual analytics best practices

Balancing analysis of multiple years by filtering through the same month/day as today
 
 
Topics in this example
 
1) With a line chart, by placing Year(Order Date) on the Color shelf and Month(Date) on the columns, you can easily compare multiple years on the same pane of the graph. Just use Running Totals from the Quick Table Calculation dialog.
 
2) If this were real-world data, you would likely want to keep data through today; otherwise, prior years would likely be much higher since they are based on a full month while this year’s latest month is partially complete, unless it is the last day of the month!
 
3) By creating a calculated field that can check if the month/day is before today’s month/day and placing it on the filter shelf and selecting True, you can keep year-to-date data Continue reading

Quick tutorial on reference lines, bands and distributions – visual analytics best practices

The following article features Tableau 6

Reference lines, bands or distributions may be added to your views to emphasize particular values or areas that may be useful in interpreting your data. In particular, when comparing multiple groups or categories of data, reference lines and bands provide immediate feedback on the overall differences between the groups.

Reference lines

Reference lines are vertical or horizontal lines displayed on your view that mark requested values such as average, median, minimum, maximum, sum, total and constants (such as a line that separates the data points as being above or below a target). They can be added on any continuous axis.

1) Open the Sample – Coffee Chain (Access) data source included by default with Tableau 6

2) Place Sales on the Columns shelf and change the aggregate to Average.

3) Place Product on the Rows shelf,
     State and Date on the Level of Detail shelf
     and format
Date to ‘MMMM YYYY’.
