Editor plugin for privately hosted charts
Take the editor interface from the cloud product and provide it as an optional library for privately hosted charts. Therefore, we can allow our users to dynamically format a chart (according to what we want to allow) with hooks so that we can privately save their changes.
For example, I want to allow users to customize the series color, marker size, style, etc. I can build my own web interface to collect/store these settings, but it would be great if there was a canned one that I can just plug in and capture the changes.
