Why doesn't the Kubernetes dashboard display utilization graphs?

When you access the Kubernetes dashboard, utilization graphs don't display.

Sometimes after a cluster update or worker node reboot, the kube-dashboard pod does not update.

Delete the kube-dashboard pod to force a restart. The pod is re-created with RBAC policies to access heapster for utilization information.

```sh {: pre}
kubectl delete pod -n kube-system $(kubectl get pod -n kube-system --selector=k8s-app=kubernetes-dashboard -o jsonpath='{.items..metadata.name}')
```
