I'm relatively new to D3 and have been following a few pie chart tutorials.

Namely the Mike Bostock Tutorials. <http://bl.ocks.org/mbostock/1346410> 

But I have question about a donut chart updating from one data set to another with the 2nd data set having much more values than the first.

I have attempted this numerous times through an update function but no luck, I'll keep it simple and give a hypothetical example , lets say my first data set had 5 values

```
[1,2,3,4,5]

```

and my second data set had 10 values

```
[1,2,3,4,5,6,7,8,9,10]

```

only 5 values of the new data set would be depicted on the arcs after the dynamic update. It's like the pie is fixed with only 5 arc sections being able to display 5 values of the new dataset.

Any help would be appreciated as its been stumbling around with the idea for awhile!
