Parallel coordinates is a long established method of visualizing multivariate data. QlikView will display a parallel coordinate chart and a user can interact with the data, but sometimes it is useful to allow the user to "brush" the data, selecting different values and seeing those values versus the whole of the data.
We can do this by using two almost identical charts with one being transparent and sitting over the other.
We need to download some data for this from the United States Census QuickFacts website. Go to http://quickfacts.census.gov/qfd/download_data.html and download the first three files on offer:
