extracting data series from *.fig file

open data.fig %open your fig file, data is the name I gave to my file
D=get(gca,'Children'); %get the handle of the line object
XData=get(D,'XData'); %get the x data
YData=get(D,'YData'); %get the y data
Data=[XData' YData']; %join the x and y data on one array nx2
%Data=[XData;YData]; %join the x and y data on one array 2xn

err.. tried it, it tells me

>> D=get(gca,'Children');
>> XData=get(D,'XData');
??? Error using ==> get
Invalid property found.
Object Name :  hggroup
Property Name :  'XData'.

It's MATLAB 7.10.0 (R2010a)

This code generated an error:

openfig(figureFile);
D = get(gca,'Children');
Child = get(D);
??? Error using ==> get
Objects must all be instances of the same class.

在 MATLAB Online 中打开

hfig = openfig(figureFile);
d = findall(hfig, '-property', 'xdata');
xydatas = arrayfun(@(h) get(h, {'xdata','ydata', 'type'}), d, 'Uniform', 0);

Now xydatas will be a cell array with one entry for each object in the plot that has an xdata property. Each of the cells will have three elements: the xdata information, the ydata information, and the name of the type of the object. Different kinds of objects might be included, depending on what was drawn in the plot.

The original question is not precise about what kind of 2D plot is present. For example, lines, surfaces, patches, and scatter plots are all 2D plots that have xdata properties.
