Hi Sean,
Typically, the popular graphs that show up on the data set page are
the graphs that have the most views. It looks like there was a bug in
the system. Our engineers fixed the problem today, so your graph on
Olympic medals should now show up on the data set overview page.
In response to your question about sorting by series, Swivel doesn't
currently support that feature. You can, however, sort the entire
chart by highest, lowest, or alphabetically. To do so, just click on
the "more options" link above the graph, and you can play around with
sorting the graph that way.
You can also sort the columns individually in the table view (http://
www.swivel.com/data_columns/spreadsheet/8970552) by clicking on the
the column header.
Hope this helps! If you have any other questions, please let me know.
We're always working to make Swivel better and we really appreciate
your feedback.
Best,
Natalie Glatzel
