MATLAB: Load data from doted plot

data importdotMATLABplot

hey I'm trying to import the data from a doted plot i made from a script to have the values show as a list instead but don't really know where to look.
I've tried
h = findobj(gca, 'Type','dot')
doesn't work only gives an empty table when the figure is open
h = importdata('case1 SOC noV2G.fig')
gives nothing of value that i can use
the plot looks like the attached file it has a seperate dot at each point of time
don't know where to go from here all help would be appriciated!

Try this: 
F = openfig('case1 SOC noV2G.fig');
h = findobj(F, 'Type','line');
for k = 1:numel(h)
    x{k} = h(k).XData;
    y{k} = h(k).YData;
end
Then go do something else for a few minutes, since this is going to take a while!
