Why Do Counts Aggregate Differently in Spotfire?

Last week, I wrote a post on using Axis Names on Cross Tables. My examples calculated the difference in Amounts between two scenarios on a cross table. I also needed to know the difference in well counts between scenarios, this time on a bar chart. But, when I changed the aggregation from a Sum to a CountDistinct, the calculations didn’t work anymore. That is because counts aggregate differently than the other aggregation methods. Read on if you want to get your counts right!

Calculate the Last Value on a Visualization

Spotfire’s label functionality leaves a lot to be desired. You can turn on all labels, which will probably clutter the chart since you can’t move labels on most charts. Or, you can mark data points to see select labels. None of this is helpful if you want specific labels on an exported report, which is where I found myself last week. To get around Spotfire limitations and still fulfill my customer requirements, I opted to add a text area with a calculated value above my visualization. This allowed me to calculate the last value from a visualization without dealing with labels. My calculation was cumulative, so I expected that if I used the same calculation, the end result would be the last value on my visualization. It was not. Even TIBCO support was stumped as to why this didn’t work. Read on to learn a little bit more about calculated values and the Spotfire expression language.

Spotfire Axis Names on Bar Charts

Last week, I introduced the concept of Axis Names. If I counted correctly, there are 19 axis names applicable to one or more of the 14 visualizations in Spotfire. I will go through the axis names one visualization at a time, beginning with axis names on bar charts. Although, I learned very quickly that just because you can use an axis name on a given visualization, it doesn’t mean you should. I’ll show you what I mean by looking at Axis.X and Axis.Color.

Node Navigation – FirstNode, LastNode, LastPeriods, PreviousPeriod & NextPeriod

This is post 8 in my series on learning the Spotfire expression language. We are in the middle of exploring all of the node navigation methods. This post will cover FirstNode, LastNode, LastPeriods, PreviousPeriod and NextPeriod. I’m combining these particular methods in order to differentiate between Node, Period, and Periods. Read on to learn the difference.

Node Navigation – All, Next, Previous, AllNext & AllPrevious

This is post 7 in my series on how to learn the Spotfire expression language. In my node navigation post, I explained what a node is, what node navigation is used for, and provided examples. But, I didn’t provide explanations or examples for each method. Now, I will fill that gap by explaining the details of All, Next, Previous, AllNext & AllPrevious.  Others to follow.
