You sent me a link to your data here: https://codap.concord.org/app/static/dg/en/cert/index.html#shared=https%3A%2F%2Fcfm-shared.concord.org%2FPrzgG6tnHTtekJ1Uz1MR%2Ffile.json The issue is that the values in “Deer Population” have commas in them so CODAP is interpreting those as text rather than numbers. When you try to use “Deer Population” on a graph axis it is treating each number as it’s own category, not a numerical value on the y-axis.You can address this in two ways.

  1. You can click on the y-axis and choose “Treat as numerical” which will create a scatterplot and you’ll have the connecting line option.
  2. You can click on the attribute name in the table (the table header for the Deer Population column) and then select “Edit attribute properties“, after which you can set the attribute “Type” to be “numeric.” Once you do that all future graphs will treat this attribute as numeric, so you can remake the graph.
