One of the first temptations in using an information link is to incorporate a Document Property that you set in the analysis. This allows the user to input a date, refresh the data, and receive a subset of the data. This is especially valuable when dealing with data sets with rows that number in the millions. These parameterized information links become very important and I wanted to share with you a quick “gotcha” in the process.

The client wanted the Y- axis ordered by the date of the first occurrence of an event. As the chart descended on the Y-Axis, the values would get larger on the X-axis. To do so took some trickery and an outsmarting of Spotfire–the methods which I will share here. Solving the problem left me with two learned lessons:
