For example, Pie Charts only show distribution, but not actual Metric values unless you hover over the slice (task). Annotations aren't visible unless you can click on the icon. Line/ Bar Charts can't show the actual metric value on a specific day like you can when hovering over the place on the graph.
It would be good if you could toggle between percentages and raw values for Pie charts.
Instead of having to put the mouse on each bar or dot of a graph to see what number it corresponds to, I would love to be able to see all numbers right away.
