Automatic text wrapping in Tikz bar charts?

Question

I am trying to get multiple bar charts (4 per page) in a LaTeX document. The issue is with the title and label text of some charts. It's showing results of a survey, some questions had long text and response text. Is there a way to get a tikz chart to 'automagically' line break/wrap the text of questions or responses? I've tried manually adding \\ but that doesn't work and is problematic because I am using a macro from spreadsheet to programatically create the TeX code anyway so can't necessarily manually add \\ or other break characters. It would be ideal if PGF/TikZ/LaTeX could automatically wrap text to make it fit.

Here's an MWE without showing the 4 charts per page but the problem is still evident. Any help would be appreciated. Thanks.

There are a some of packages in your MWE that have nothing to do with the plot, so I removed them from the code below. I also added the missing \makeatother after the block with \pgfdeclarepatternformonly.

To have line breaks in the title, you can use the option title style, to style the y ticks, use y tick label style. You essentially need to tell PGF that you want the contents of the text node to align (right, center or left) and specify a concrete (maximum) text width. Line breaking will then be applied automatically.

You may want to adjust the spacing a bit. Above all, you need to increase the height of the plot if the y labels contain line breaks.
