Master NavigatePeriod Node Navigation

This post will wrap up a lengthy discussion of Spotfire’s node navigation methods by explaining how to use NavigatePeriod. Now, you might have noticed, node navigation methods like FirstNode, LastNode, and Parent are fairly restrictive. They point to one place and one place only. NavigatePeriod makes up for that with greater flexibility. Let’s learn how to master NavigatePeriod.

Syntax

To begin, let’s look at the syntax. Navigate Period has three mandatory arguments and a fourth optional argument. I’ve copied and pasted the TIBCO descriptions of the arguments below. They aren’t the easiest to understand but don’t worry. The video below contains plenty of examples. The only thing you need to know before we get going is that arguments 2 and 4 can be written as a string or as an integer. You’ll see examples of both.

  • First, arg1 is the hierarchy to navigate.
  • Second, arg2 is a string or integer value specifying the level in the hierarchy that you should navigate up to.
  • Then, arg3 is an integer specifying the number of steps to move sideways in the hierarchy at the level specified by Arg1.
  • Finally, arg4 is optional and determines the level in the hierarchy to move down to.

NavigatePeriod has many nuances and is best explained in a video. If you are already familiar with the basic syntax skip forward to min 2:40. If you feel like 13 minutes is too long, skip to then where I explain how to calculate a YTD average where the calculation restarts the average with each year.

Wrap Up

I hope you found the video useful. I couldn’t have put it together without a little bit of help from TIBCO support, so I would like to thank Khushboo Rabadia for being patient with me as I struggled through learning the details of NavigatePeriod.

In conclusion, learning to master NavigatePeriod isn’t easy. But, once you know how to use it, I bet you’ll be performing more of your calculations on visualizations. Finally, there aren’t a lot of resources out there explaining NavigatePeriod, so I would greatly appreciate it if you would spread this link around.
