To be able to clarify the user what is being displayed in the line chart, I would like to display a legend within the line chart. Something like this:
Note: I realize this post is similar to: https://community.aimms.com/aimms-developer-12/how-can-i-show-the-legend-on-a-webui-linechart-263 . But in that post, the solution suggested is to create a separate legend widget and style it through css. We choose not to apply that solution/work-around, because is will clutter the look and feel of the page too much.
