plots location-specific data at each location of the visual field. It is the function called by vfplot

locations where to plot symbols, the TD and PD values
color to apply to each location. Typically calculated from the normative values

Hull defined for the visual field test.
minimum and maximum limits on the x and y axes, in degrees of visual angle.
font of the text with visual-sensitivity values. Default is sans
size of the text with visual-sensitivity values. Default is 10
Whether to show axis or not. Default is FALSE
Color of the axis to show, if showaxis is TRUE. Default is black
The vfplot function operates on a single row of visual fileds (vf). Depending on the plot type it will generate a plot representing the sensitivity at each location. The color scheme elucidates the degree of sensitivity at that location. Locations with zero sensitivity are shown in black. Blind spots have been excluded fronm the plot
