visualisation for utility usage sought

Hi All,

I hope this isn't considered off topic here, but this has been bugging me for a while and I reckon you guys may be able to help. To boot, I'd like to use matplotlib to make it happen, so I figure this list is fair game :wink:

So, I have a series of measurements at points in time, eg:

2007/09/01 - 5000
2008/01/01 - 8000
2008/02/01 - 9000

...and I'm looking to create some type of visualisation that indicates usage over time.

The import point is that the gaps between point measurements are not constant, so a straight bar chart won't be right.

The points also won't necessarilly be as convenient as those above, but hopefully they'll work as an example: What I'd expect to see would indicate that the monthly usage between September 1st and January 1st was, on average, the same as that between January 1st and February 1st.

I'm having trouble expressing myself clearly, but hopefully I'm making some kind of sense.

Any ideas very greatfully recieved!

cheers,

Chris
