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!Read More »Why Do Counts Aggregate Differently in Spotfire?
Learning the Spotfire Expression Language
Working with custom expressions in Spotfire can be tricky. You try different combinations of syntax and just get errors. Sometimes the error message is helpful, but often it is just jibberish. How do you know exactly what’s getting passed thru the expression? There is a way to find out. Check out this short post for a solid pro-tip on troubleshooting custom expressions in Spotfire.Read More »Troubleshooting Custom Expressions in Spotfire
If you’ve been following along, you know that my series on learning the Spotfire expression language is something of a long haul. It turns out that explaining Axis Names is a long and detailed affair. I am committed to it, and so this week I’m going thru axis names for line charts. If you missed it, check out Axis Names on Bar Charts.Read More »Spotfire Axis Names on Line 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.

A while ago, I started a series on learning the Spotfire expression language. I made a lot of progress on it but got pulled off on a few side quests. This week, I return to that theme with an explanation of how to use the $esc and $map functions in Spotfire. Knowing how to use these functions will allow you to connect visualizations to property control to provide a more interactive experience for users. It will also give you greater insight into how Spotfire expressions really work. Read on if you want to be able to…
- Create dynamic visualizations that update with changes to property controls.
- Use data limiting with property controls.
This is post 9 in my series on how to learn the Spotfire expression language. It explains the Parent and ParallelPeriod node navigation methods. Originally, I included NavigatePeriod, but NavigatePeriod deserves its own post, so it will follow next week. Read on to learn about Parent and ParallelPeriod node navigation methods.Read More »Node Navigation – Parent & ParallelPeriod
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.Read More »Node Navigation – FirstNode, LastNode, LastPeriods, PreviousPeriod & NextPeriod
