cannot extract data from figure with multiple lines

5 views (last 30 days)
Hello,
I have a matlab figure with muliple lines in it that I am trying to extact. However I can only get the figure line. I am not sure what is wrong. I created the figures in simulink
I am using the following code
fig = openfig('traj.fig');
h = findobj(gca,'Type','line');
y_no_humanX = get(h,'Xdata') ;
y_no_humanY = get(h,'Ydata') ;
close(fig);
when I try to extract the data I only get the first line and cannot get the other lines. I am not sure what is going on.
Any ideas?

The other two "curves" are created using stairs(). use findobj(fig,'Type','Stair') to find those.
fig = openfig('traj.fig');
>> findobj(fig)
ans =
12×1 graphics array:
Figure (ScopePrintToFigure)
UIContainer (PrintLayoutGridContainer)
UIContainer (PrintContainer)
Panel (DisplayPanel1)
Legend (ref, Subsystem/1, Subsystem/3)
Axes (DisplayAxes1_RealMag)
Stair (DisplayLine2)
Stair (DisplayLine1)
Line (DisplayLine1)

If you have access to the Simulink model and simulation, you could save those data directly using the "To Workspace" block.
