how do i format the value shown in a d3 graph

Question

I am trying to change the formatting on the value shown on top of the bar graph in a nvd3 discrete bar graph. I believe I am doing something wrong, I have no idea. Here is the js fiddle for the graph http://jsfiddle.net/looneydoodle/PdpRq/ Here is the code ``` var basicformat = d3.format(',f'); d3graph.selectAll('g.nv-bar text').each(function(d,i){ this.text(basicformat(this.value)); }); ``` EDIT: Figured out how to do it, although it might be a bad way to do it. Here is the updated fiddle: http://jsfiddle.net/looneydoodle/PdpRq/2/

Accepted Answer

Looks like the discreteBarChart has a `valueFormat()` method. You can sorta see it defined in the nvd3 source on line 232.

So, to set a format other than the default that you're seeing, all you need is:

```
chart.valueFormat(d3.format('f'))// Or whatever format you'd like
```
