   1 # For a minimal bar plot you have set an bar axis
   2 # in the graph constructor and provide Xname column
   3 # data (X stands for the bar axis to be used).
   4 # Furthermore you need to specify the graph style,
   5 # since the default graph styles symbol and function
   6 # (depending on the data type) are not appropriate
   7 # for this case.
