    • getDataRange

      public Range getDataRange(ValueAxis axis)
      Returns a range representing the extent of the data values in this plot (obtained from the subplots) that will be rendered against the specified axis. NOTE: This method is intended for internal JFreeChart use, and is public only so that code in the axis classes can call it. Since only the range axis is shared between subplots, the JFreeChart code will only call this method for the range values (although this is not checked/enforced).
      Specified by:
      getDataRange in interface ValueAxisPlot
      Overrides:
      getDataRange in class XYPlot
      Parameters:
      axis - the axis.

      The range.

      space - the space.
