When you are viewing the results of a query, you can plot any
numerical column against any other numerical column by clicking
the Plot button at the bottom of the table of results. All
displayed rows are included in the plot - clicking the checkboxes
by each row has no effect.
A new page will display with a plot form.
Change the defaults if desired - the default is a scatter plot
of ra vs dec.
Click Plot to view the plot.
Clicking Plot Options will bring you back to the plot form.
