HeyHo, i have create a function that gives me 9 subplots. Now I want to get all the y Values and write them into ONE big Array. How do i do it ?

 Data = findobj('type','axes')
 Data = sort(Data)
         for i = 1:length(Data)
             PlotLines = get(Data(i),'children')
             PlotLines = sort(PlotLines)
             yValues = get(PlotLines(3),'ydata')
             %StoreArray(i) = yValues %%does not work
         end

I go into every axes handel, take its children and get the yValues. Now i want to store them in one Array.Pls try to use my given Code to help me but feel free to optimize it.

在 MATLAB Online 中打开

You plotted the data, right? So why don't you already have it and need to extract it from the axes? You should. So then you just do

StoreArray = [y1,y2,y3,y4,y5,y6,y7,y8,y9];

If you insist on your way, do this:

StoreArray = [StoreArray , yValues];

Be sure to inatialize StoreArray before the loop begins to null

StoreArray =[];

Thanks alot.....the reason i am using this kind of solution is.... well my program is far to complicated and i want this part to be as easy as it could be. Using the original Plot data is no choise for me. But Thanks
