Custom Dimensions: How to show in Visitor Profile, how to change chart type in widget?

I am using Custom Dimensions and I ran into two questions:

  1. Is there a way how to display the custom (visit) dimension on the Visitor Profile (which opens from the log). It is possible to show the visitors segment for a dimension, so it should be possible.
  2. I don’t manage to display the dimension as a graph that shows the development over time (one graph for each value or for selected values, or a “stacked area” where all values add up to 100%). Is that possible and how?
