class PlotData(object):
    """
    Class used for managing plot data
      - allows data sharing between multiple graphics items (curve, scatter, graph..)
      - each item may define the columns it needs
      - column groupings ('pos' or x, y, z)
      - efficiently appendable 
      - log, fft transformations
      - color mode conversion (float/byte/qcolor)
      - pen/brush conversion
      - per-field cached masking
        - allows multiple masking fields (different graphics need to mask on different criteria) 
        - removal of nan/inf values
      - option for single value shared by entire column
      - cached downsampling
      - cached min / max / hasnan / isuniform
