Delete all nodes and relationships in neo4j 1.8

Question

I know this question is asked by many people already
for my research, here's some questions asked before

1. How to delete all relationships in neo4j graph?
2. https://groups.google.com/forum/#!topic/neo4j/lgIaESPgUgE

But after all, still can't solve our problems,
we just want to delete "ALL" nodes and "ALL" relationships

suppose delete "ALL" can see there are left 0 nodes 0 properties and 0 relationships

This is the screenshot i took after executing the delete "ALL" suggested by forum

My question still the same, how do delete all nodes and all relationships in neo4j
