I'm wanting to build a tool that graphs historical data, so you can compare hourly values for yesterday, the same day a week ago and the same day a year ago. This would let me visually compare the hourly values (so 24/day) for yesterday, etc.

 

I know this can be done in Excel, so I hope the web API can do this.

 

If not, is there another API I can use that can do this?
