Delete all nodes and relationships in neo4j 1.8


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

enter image description here

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
