function gsp_plot_jtv_signal(G,signal,param)
%GSP_PLOT_JTV_SIGNAL Plot a time-vertex signal in 2D or 3D
% Usage: gsp_plot_jtv_signal(G,signal);
% gsp_plot_jtv_signal(G,signal,param);
%
% Input parameters:
% G : Time-Vertex graph structure.
% signal : Time-Vertex signal.
% param : Optional variable containing additional parameters.
% Output parameters:
% none
%
% 'gsp_plot_jtv_signal(G,signal)' plots a time-vertex signal in 2D or 3D,
% using the adjacency matrix (G.A), the plotting coordinates (G.coords),
% the coordinate limits (G.plotting.limits), the edge width
% (G.plotting.edge_width), the edge color (G.plotting.edge_color), the
% edge style (G.plotting.edge_style), and the vertex size
% (G.vertex_size). If the figure loses the focus the visualization will
% stop
%
% Example:
%
% G = gsp_sensor();
% G = gsp_jtv_graph(G,50);
% f = sin(2*pi/G.N*(1:G.N)'*[1:G.jtv.T]);
% gsp_plot_jtv_signal(G,f)
%
% Additional parameters
% ---------------------
%
% param.step : Time step (default round(log(param.T)))
% param.T : Final time (use if you want to visualize only the first param.T samples)
% param.show_edges : Set to 0 to only draw the vertices. (default 0, really slow )
% param.cp : Camera position for a 3D graph.
% param.vertex_size*: Size of circle representing each signal component.
% param.colorbar : Set to 0 to not show the colorbar
% param.climits : Limits of the colorbar
% param.vertex_highlight*: Vector of indices of vertices to be highlighted
% param.bar : 1 Display bar for the graph. 0 Display color
% points. (default 0);
% param.bar_width : Width of the bar (default 1)
% param.clear : Clear axes (default 1)
