Count curves on Matlab plot with specific name

Is there a way to count how many curves are on a specific Matlab Figure? I define the name of plot as
figure('Name','Simulation', 'NumberTitle', 'Off')
Since I have multiple plots generated at various times I am unable to use gcf. What I would like to do is something like
length(findall('type','line','Name','Simulation')
to find all curves associated with the plot (or plots) named Simulation.

I saw the one suggestions of using
length(findall(gca,'type','line'))
but as I said earlier I need to use that on all figures using one axis not necessarily the current axis.

You can try
hFigure = findall(0,'type','figure','name','Simulation')
That should give you the handle to all figures with the name Simulation. you can then do:
hLines = findall(hFigure,'type','line')
which should give you all the lines.
If you don't like decorating your figures with unique names, you can also use the 'tag' property on your lines, axes, whatever and search for that. Nothing user-visible, just something you can use to search against.
