Now full MOT results are available I have the ability to sort out mileage graphs. I'm looking to present them in a few formats:
- Line graph - showing current mileage over time
- Variable width bar chart - showing average mileage per month over time
- Yearly bar chart - showing estimated yearly mileage
The code to get together data for these statistics is already done - so all I need to do is get the graphs to be generated. I've been looking at Google Chart API and Open Flash Chart. Google's offering is pretty easy to use but seems a bit odd in that its bad at figuring out how to scale bar charts. OFC on the other hand seems a bit more powerful (you can add your own shapes to charts and do some other nice things) but code wise its a bit of a pain. I'm playing with both to see which one I like more. Hopefully I can get something working soon in beta.
