Please ignore the background image. The foreground chart is what I am interested in showing using pandas or numpy or scipy (or anything in iPython). 

I have a dataframe where each row represents temperatures for a single day. 
This is an example of some rows:

```
            100   200   300   400   500   600 ...... 2300
10/3/2013  53*C  57*C  48*C  49*C  54*C  54*C        55*C
10/4/2013  45*C  47*C  48*C  49*C  50*C  52*C        57*C

```

Is there a way to get a chart that represents the changes from hour to hour using the first column as a 'zero'
