GETFIGDATA extracts the xyz data from a FIG file.

Syntax:
GETFIGDATA(filename);
[x,y,z] = GETFIGDATA(filename);
[x,y,z] = GETFIGDATA(filename,n,Type);

If the figure contains multiple axes, the axis number (n) to be used must be specified. By default, the first axis is used.
If the figure contains multiple plot types (line, scatter, etc.), the desired type must be specified, otherwise "line" will be selected by default.
Plot types can be inspected using GETFIGDATA with no output arguments.
Each data series is an element of the returned cell arrays: [x{i},y{i},z{i}] must be used to access the ith data series.

Example:
myfigfile = 'simulation_output.fig';
GETFIGDATA(myfigfile)
[x,y] = GETFIGDATA(myfigfile);
plot(x{1},y{1})
