During the Christmas holiday, I noticed this tweet from a friend, Paul Banoub: This frustration isn’t uncommon. About 25% of the clients I’ve worked with during the last seven years have underutilized Tableau initially because they didn’t use Tableau’s visual analytics (available via Show Me) to...
A bullet graph is a very powerful way to compare data against historical performance or pre-assigned thresholds. As you’ll see, we can include a lot of information in a small space with this type of chart that is also Tableau’s answer to those looking for...
During the past year, I’ve given lots of speeches and spoken with hundreds of people that are using Tableau. Many are expanding their Tableau Server deployments. Most people want to know how to ensure success or improve the utilization of the tool. They want to...
The Gantt chart was invented back in the 1910s by Mr. Henry Gantt as a way to visualize a schedule or progression of time. Since then, the Gantt chart has become a staple of project management methodology. Each task can be planned as an individual...
Tableau has two ways of coloring continuous measures: sequential and diverging gradients. The common understanding is that sequential palettes vary the intensity of one color while diverging palettes use two contrasting colors. This is generally true, but there’s much more to the story. Knowing how...
Compared to the other chart types, the box-and-whisker plot (also known as the box plot) is a bit more complicated. Before we can delve into an example of how it is used within Tableau Software, we have to explain the logic behind this type of...
A histogram is a visual representation of the distribution of data. There are two ways to create a histogram: 1. Select a single measure. Right-click on that measure to create a bin field. Drag the bin field from Dimensions to the Column shelf. Drag and drop...
The scatter plot, also known as a scatter diagram, scatter chart, scattergram or scatter graph, is useful to compare two different measures for patterns. Like the circle view and the side-by-side circle chart, the scatter plot also uses symbols to visualize data. The big difference...
The area chart is a combination between a line graph and a stacked bar chart. It shows relative proportions of totals or percentage relationships. By stacking the volume beneath the line, the chart shows the total of the fields as well as their relative size...
The Challenge Visualize movement from Date A to Date B with one dimension and two measures. More specifically, display how these measures interact with each other and affect the outcome or performance of the dimension over time. This problem was posed to me by one of...
Typical day-to-day analysis is focused on things that have happened in recent days, months or years. We seldom go far enough into the past to make us think about what to do with dates prior to “date zero” (normally, January 1, 1900). That is unless...
Because I have just that much free time, I thought I’d take a gander at my spending so far this year using Tableau. The holiday shopping season is coming up, and I wanted to know if I would have any money left to fill stockings...
To examine the side-by-side bar chart, let’s first take three rows of vertical bar charts. These represent sales volume by state and are divided into the three different departments of our fictional company. Figure 1: Vertical bar charts. That view is useful, true, but it has two...
Client requests are sometimes the best way to think outside of the box with Tableau. Sometimes you ask yourself “WHY?” and shake your head. Other times, the requests force you to come up with a creative new solution within Tableau that you’ve never come across...
The stacked bar chart is great for adding another level of detail inside of a horizontal bar chart. You can do this by adding another dimension to your horizontal bar chart that will further divide the measure into sub-groups. The sub-groups are then color-coded on...
The horizontal bar chart is a bit of a misnomer, because simply switching the axes with the Swap button in the Tableau toolbar will magically make a horizontal bar chart into a vertical bar chart! That’s actually not the crux of this chart – it is...
In my developer mind, what takes Tableau 8 from neat to amazing is the ability to manipulate, calculate and maneuver data quickly and easily. Calculated fields allow you to compare fields, apply aggregations, apply logic, concatenate strings, convert dates or perform a myriad of other analytical...
Pie charts are among the most popular, if terribly overused, charts in business presentations. They are best suited to show proportional or percentage relationships. When used in the right circumstance, pie charts can quickly show relative value to the other data points in the measure. Figure...
We’ve already covered the other type of map view in the symbol map article. Now, let’s look at the filled map chart type. The filled map is another view ideal for geographic data. Instead of circles or squares to display data points, the filled map uses...
I’ve seen it a dozen times in classes that I have taught. A student is digging Tableau (who doesn’t?) and all of the ways that it can present data. While working through the classroom examples, everything is going smoothly. Then, someone connects to their own...
