Bootstrap 3.0 - Vertically align 3 panels in the same row (Auto Height)

Trying to have a single row of 3 panels where the height expands according
to the content and they all align properly. The left panel would have a
graph in it, the two on the right would have tables that work with the
graph on the left.

Example of this working is this template: Click Here For Example
<div class="row">
<div class="col-md-8">
<div class="panel panel-default">
<div class="panel-heading">
