The zoome slider in Spotfire is set up to zoom in and out when the mouse wheel is moved (hence the name). While this might be useful to target a bit of the data, it prevents us from easily navigating up and down a large list of categories.
On all of our organisation's spotfire dashboards, we have a scrollable list of 'things', and a measure. This is a hack of the graphical table where we use the colour ranges to represent the bar length. It requires a lot of hacking, and it would be better to change the behaviour of the zoom slider to just scroll with the mouse wheel instead of zoom.
