Count the number of times I have plotted to a Figure

I use

 h =  findobj('type','figure');
  n_Fig = length(h)

to determine the number of open figures,

however, I want to know if I already have plotted to a specfic figure.Number

 Plot_use_count = 0;

when I plot to figure.Number (what goes here???)

Plot_use_count = Plot_use_count +1
end

I use figure(Fig_Num) as way for the GUI user to define which figure to plot to.

then I use text

      XLim = xlim; YLim = ylim;
      X_range = XLim(2) - XLim(1);
      Y_range = YLim(2) - YLim(1);
      X_text = XLim(1) + 0.02.*X_range;
      Y_text = YLim(1) + (0.1.*Y_range + 0.1.*Y_range.*Plot_use_count);
      text(X_text,Y_text,Str_Variable)

to place text on the plot. This works fine for the 1st time Fig_Num is used, but if re-used (i.e. has the same value), the the text is overwritten, rather than

current_count = get(Fig_num, 'UserData');
if isempty(current_count); current_count = 0; end
current_count = current_count + 1;
set(Fig_num, 'UserData', current_count);
