Order data in charts by dependent variable (x-axis), not independent variable (y-axis)

If the x-axis consists of nominal values, e.g. financial years ("2010-11", "2011-12" and so on), the values in the bar chart are sorted by y-axis values. Values should be sorted by x-axis first (if the x-axis is not a continuous scale, then use alphabetical order, which would work on the example of financial years).
