Specificities bar chart, add "group bars by lines / transpose" button.

h3. Validation tests

* create some bar chart from specificities table
* use the "Group bars by line" tool bar button => the matrix must be transposed AND the new chart must be entire visible in the editor (a reset view is done but I had some trouble leading to the new chart was not entirely visible after transposing the matrix)
