Improve Qualitative Chart

[laceysanderson]

I would love to make vertical bar charts! These would mimic the layout of the violin plots with sites years on the x-axis, categories on the y-axis and number of germplasm being the length of the bar. This would make the charts less disorienting when switching between traits. It would also be less cluttered and I feel easier to make comparisons between categories. However, I have yet to find such a chart so it would be a labour of love.
