Currently, no; if you want percentages, the pie view provides this. In future we'll update the bar view to provide the same option.

Summary of this idea:

Allow you to choose to show percentages instead of / as well as actual values in the bar view.

These would initially be percentages of the entire view, so if you were paning in several dimensions, you would see quite small percentages, and all panes would add up to 100%. This would match the option in the Pie view.

In future we could allow you to control what level the percentages were of - e.g. allowing you to normalise each pane to 100%, like we currently do for stacked bars with "100% bars" enabled.

Is this idea realized in the meantime? I still miss the funktion of showing at least the total value in the graph view for each measure when switching to the 100%-view for stacked items.

% in bars is in development in 2.8.

The total value can still be shown. In the Measures menu, see "Show overall value in data titles / toolbar".

That again leads to the question, when version 2.8 will be released.

Yes I'm awware of that function, but it is not really adequate for our presentation, as we hide the data title and the relevant toolbar-field. Instead of showing 100% at the top of the bar it would be more informative to show the total value for some measures.

2.8 has major work planned and we cannot give a concrete time-frame, but are currently aiming for late summer.

You should add a small Content View with the same data subset above the Bar view containing a formula/function-driven value using the f button.

Use "View toolbar > Tools > Fix view size > Fix height" to lock the height of the content view regardless of window size.
