I assume that you have the frequency response data for a system and want to get the Transfer Function coefficients for the system. try using the INVFREQS function.

What form is the graph in? If it is in handle graphics form,
plothand = findobj('type','line');
wd = get(plothand,'XData')
hd = get(plothand,'YData')
However, I see that invfreqs expects to have complex responses input in to it, but it is not possible for the XData or YData to come out complex. You would have to figure out how to deduce the complex response from the graph.
