feature request - percentage graph

[fl-ma]

As a user, I would like to get an overview of how often I achieved a specific goal over a certain time. E.g. how often did I exercise in the last 10 days. Data input:

• number per date (either 1/0 if I just want yes now; any numeric number, e.g. minutes of workout)
• reference number (when is a day considered 'done', e.g. 60 for an hour exercise)

Output graph:

• percentage over the days (number of days 'goals achieved' in relation to days overall)

Example:

This is probably a separate graph type. Unfortunately I don't have much development time on my hands these days and there are higher priorities. I will leave it here though in case someone else is interested in taking it on.
