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

The compact form of this example was also featured on The Guardian DataBlog, the third most popular online newspaper in the world.

Bullet charts and simple enhancements to maximize value

Bullet charts were added to Tableau in version 5.1. They are an original idea designed and advocated for by Stephen Few, at the University of California at Berkeley. The bullet chart is intended to enable easy examination of attainment relative to a target for categorical items.
 
According to Stephen’s original specification, “The bullet graph was developed to replace the meters and gauges that are often used on dashboards. Its linear and no-frills design provides a rich display of data in a small space, which is essential on a dashboard.

I have shown the standard Tableau bullet chart and a wide array of variants in our public training course. Based on extensive attendee feedback, I will share how just a few minutes spent enriching your bullet charts will yield powerful enhancements for your dashboard audience.

SAT performance versus school spending dashboard

This dashboard provides a comparison of per student spending with performance on the SAT exam based on the 2009 New Jersey Report Card data. DFGs are based on economic and demographic data. These are assigned by the New Jersey State Department of Education.

This work was created in collaboration with Bob Morrison of Quadrant Arts Education Research. Bob has extensive experience with helping school systems measure educational results related to how and where funds are spent. I have a great admiration for Bob as a passionate advocate for growing both music and arts education. Bob has expertise in advocating on behalf of students around the many ways that music and arts education can engage students and improve their academic performance.
