[Ax,Lhs,Rhs] = plotcmp(X,...)
[Ax,Lhs,Rhs] = plotcmp(Range,X,...)
Range [ numeric ] - Date range; if not specified the entire range of the input tseries object will be plotted.
X [ tseries ] - Tseries object with two or more columns; the difference (between the second and the first column (or any other linear combination of its columns specified through the option 'compare=') will be displayed as an RHS area or bar graph.
Ax [ handle | numeric ] - Handles to the LHS and RHS axes.
Lhs [ handle | numeric ] - Handles to the two original lines.
Rhs [ handle | numeric ] - Handles to the area or bar difference graph.
'baseLine=' [ true | false ] - Draw a baseline in the bar/area difference graph.
'compare=' [ numeric | [-1;1] ] - Linear combination of the observations that will be plotted in the RHS graph; [-1;1] means a difference between the second series and the first series, X{:,2}-X{:,1}.
'cmpColor=' [ numeric | [1,0.75,0.75] ] - Color that will be used to plot the area or bar difference (comparison) graph.
'cmpPlotFunc=' [ @area | @bar ] - Function that will be used to plot the difference (comparision) data on the RHS.
