Datagraph allows to plot a number of graphs which are based on the Zernike coefficient data.
All Zernike based graphs can be shown for entire eye or Ocular ('O'), Internal ('I') or Corneal ('C') aberration data according to their labeling in the type column on the aberration data tab.
Since RMS values depend on pupil diameters graphs are also filtered by their pupil diameter.
Note: There are additional options on the graph filter window when displaying any type of WF based graphs. You may select Corneal, Internal and Ocular aberration data under 'ab Type' and display graphy for different pupil diameters (selectable under 'diameter'). Comparing outcomes of different patient groups must be done for the same pupil diameter.
