UVPLOT is the jGraph module of jLab.

 UVPLOT  Plots the real and imaginary parts of a signal on the same axis.
    UVPLOT(T,CV) plots the real and imaginary components of the
    complex-valued data CV=U+iV versus time T.  Here T is a column
    vector and CV is a matrix with LENGTH(T) rows.
    UVPLOT(T,CV,STY1,STY2) optionally plots the real components of CV,
    U, using style STY1, and the imaginary components V using STY2.
    STY1 and STY2 are strings following the format in LINESTYLE.
    UVPLOT(T,CV,STY) uses STY for the linestyles of both lines.
    UVPLOT(T,U,V,...), where U and V are real matrices, also works.  
    [H1,H2]=UVPLOT(...) returns handles to the line plots of U and V.
    As an example,
         load bravo94
         uvplot(num,cv,'2b','r-.'),xlim([120 340])
    returns a color version of Fig.4b of Lilly and Rhines JPO 2001.
    Usage:  uvplot(t,cv);
