PlotChart: plots the interference chart

Description

PlotChart plots the result of a call to InterferenceTable

Usage

PlotChart(IC, type = "Sorensen", Thickness = 30, x.lims = NULL,
  radials = FALSE)

Arguments

IC

Dataframe from InterferenceTable.

type

Chart type (see Details).

Thickness

If not NULL, a horizontal line is drawn at h= Thickness (in micrometers).

x.lims

Plotting range, horizontal axis (when NULL, defaults to c(0,0.05) for Raith-Sorensen plots and to c(0,2500) for Michel-Levy plots).

radials

If TRUE iso-birefringence lines will be plotted (on Michel-Levy chart only).

Value

a Sorensen or Michel-Levy plot

Details

If type belongs to c("Sorensen","S","Raith-Sorensen","RS"), the function plots interference colors on a grid with birefringence as horizontal axis and thickness as vertical axis. If type belongs to c("Michel-Levy","ML","MichelLevy","M"), the horizontal axis is retardation (in nanometers) as in the classical Michel-Levy plot. When radials is set to TRUE, birefringence appears as oblique lines with rounded values printed at their end
