overwrite an existing GUI

good night everybody, is there anyone that knows anyfunction to count number of opened graphs because in my GUI, in the 1st interfaace I have a pusbutton and it is generating variables on another interface depends on the values entered by the user. When user wants to generate any other variables I want to overwrite the existing one so I guess it maybe possible to know the amount of figures and close all except 1st one, or how can I overwrite an existing table, I could not check the handle of table because handle is erased just after creation or not exist before execution for any suggestion thanks in advance good weekends

figurehandles = findall(0, '-type', 'figure');
number_of_figures_open = length(figurehandles);

[Metin]

it gives an error of:

   Invalid Parameter-value pairs passed to findall.
Error in ==> GUI_Module>ButtonCalculate at 69
        h = findall(0, '-type', 'figure');

Thanks for answer

Darn syntax is inconsistent. But you would have seen correct syntax if you had looked at the "findall" documentation.

figurehandles = findall(0, 'type', 'figure');

good morning, yes it wright but for my program still I could't reach the point what I want because as by pushing button I want to generate the variable table on the previous one to prevent many figures on the screen, and with this comment as I have to check number of figures before generation I lose my actual handle and because of function itself not possible to assign another value to the result of findall, there has to any other simple solution to overwrite an already existing figure but I don't know, for any other further suggestion thanks in advance

Have you considered tagging the graphic object you want to write into?

For example if you put all the relevant objects into a uipanel, then at the time of creation,

set(HandleOfUiPanel, 'Tag', 'ResultsPanel');

and then when you want to find it again,

HandleOfUiPanel = findobj(0, 'Tag', 'ResultsPanel');
if isempty(HandleOfUiPanel)
  %oh... it doesn't exist at the moment! Recreate it?
end
