Possible to extract data matrix from plot figure?
in [Matlab]
|
From: Ida Haggstrom on 20 Apr 2010 08:13 Hi! I have a somewhat silly question I think... If you have a matlab figure (.fig) containing a 2D plot, is it possible to extract the matrix of X and Y values from the graph? I only have the figures, not the data.... I've tried "h = get(gca)", but I can't find anything in the handle that seems to be the actual data of the graph in the plot... This may not at all be possible, but I figured I'd ask anyway!=) Thanks! Ida

Seems I was just not looking hard enough. a = get(gca); b = h.Children; b.XData and b.YData gives me the two vectors I want! =) (b(n).XData and b(n).YData gives you graph n if you have many in the axis).
