We had several similar requests to switch on/off labels inside the stacked bars and the total label on top, so this is re-classified as an idea, that we are considering for the next version of Omniscope. Please vote for the idea: http://forums.visokio.com/discussion/1432/show-value-labels-on-top-of-bars Thanks
It would also be useful to be able to switch on/off the function next to the value at the view level. Currently this is only possible at the tab level.
