Frequency Dot Plots

Plot of Exploratory Parallel Coordinates

  • Aabel applies the method published by Leland Wilkinson* to generate dot plots, but in addition, uses modifications necessary to allow:
    • Dynamically compensating for modifying the plot aspect ratio
    • Scaling of dot size ("bin width")
    • Using ellipsoids dot when dot stacks are too cluttered by vertical overlaps (which happens if the chart pane is too small to accommodate the defined dot size)
