The lines and curves feature for some visualizations can be improved by allowing other columns (not just the one mapped to the x-axis) of the same data type to be used in computing / aggregating a result. Much like the concept of layers for GIS systems. Today, I wanted to add a vertical bar to a bar chart where the x-axis was a DateTime hierarchy, but the dates were events in time that were captured in another column. The only column I could use was the one mapped to the X-axis of the bar chart.
It would be good to not have this limitation.
