Call <A HREF="../Draw/PetscDrawBarSetData.html#PetscDrawBarSetData">PetscDrawBarSetData</A>() to provide the bins to be plotted and then <A HREF="../Draw/PetscDrawBarDraw.html#PetscDrawBarDraw">PetscDrawBarDraw</A>() to display the new plot

The difference between a bar chart, <A HREF="../Draw/PetscDrawBar.html#PetscDrawBar">PetscDrawBar</A>, and a histogram, <A HREF="../Draw/PetscDrawHG.html#PetscDrawHG">PetscDrawHG</A>, is explained here http://stattrek.com/statistics/charts/histogram.aspx?Tutorial=AP
<P>
The MPI communicator that owns the <A HREF="../Draw/PetscDraw.html#PetscDraw">PetscDraw</A> owns this <A HREF="../Draw/PetscDrawBar.html#PetscDrawBar">PetscDrawBar</A>, but the calls to set options and add data are ignored on all processes except the
zeroth MPI process in the communicator. All MPI processes in the communicator must call <A HREF="../Draw/PetscDrawBarDraw.html#PetscDrawBarDraw">PetscDrawBarDraw</A>() to display the updated graph.
