% PLOTCLAW1 is the main driver routine for plotting 1d graphs for Clawpack.
%
%    PLOTCLAW1 is the main routine that the user calls to step through a
%    series of frames (i.e. fort.tXXXX and fort.qXXXX files).
%
%    Various parameters can be set in SETPLOT1.  The default version in
%    claw/matlab/setplot1.m can be copied to your directory and modifed to
%    set things up differently, or type 'k' at the prompt to get keyboard
%    control and change a value.
%
%    See also SETPLOT, PLOTFRAME1.
