Jan 13, 2011 at 22:02 comment added glassy Grouped bar chart is always preferable to stacked bar chart, because the latter makes the comparison of different series more difficult than the former. A brief discussion about different versions of stacked bar and grouped bar plot (marimekko chart, weighted grouped bar plot, etcetera) with some links can be found here: antoniorinaldi.it/data-visualization-for-two-ways-tables-1

Changed to reflect edited question
Jan 12, 2011 at 0:58 comment added Elpezmuerto I updated to reflect I want bar plots not histograms.
Jan 11, 2011 at 21:52 comment added whuber +1 For the distinction between bar charts and histograms. (The difference becomes very clear when you consider how best to plot histograms with varying intervals, as illustrated at stata.com/support/faqs/graphics/histvary.html.)
Jan 11, 2011 at 20:50 comment added Matt Parker Excellent point - that mostly negates the concern about varying group sizes, assuming non-response is about even across the questions. I still have difficulty comparing the "slightly concerned" proportions across groups, but the horizontal layout does seem easier. That post is a great resource - thanks for linking it here.
Jan 11, 2011 at 20:39 comment added chl (+1) A possible exception is when we have a set of indicators (e.g., items in a questionnaire) with a fixed number of categories (e.g., Likert-type items), as discussed in Visualizing Likert Item Response Data, or a single crossing factor (e.g., gender), in which case an horizontal (we are better at visually discriminating along the horizontal than the vertical axis) stacked barchart might be interesting, IMO.
