Button["Reset", a = {0}]?

Does anyone know how to create a "Reset" button that will clear a ListPlot (ie: clear off the data that is plotted) but leave the Plot axes and ticks there so that it can be started again. 

Here's what I have. Basically I need to be able to clear the graph. 

ListPlot[a, Joined -> True], 
Button["Add Random", AppendTo[a, RandomInteger[{1, 6}]]], {{a, {0}}, 
ControlType -> None}, 
Button["Reset", Clear[a]]] 

Thank you,
