Hi,

I am trying to add a push button in the uitable so that I could refresh data in there.

I am not sure whether I should use refreshdata, but I am thinking about things like this (just a dummy code)

f = figure('Position',[250 100 600 550]);
t = uitable('Parent',f,'Data',dat,... 
            'Position',[20 180 306 150]);
b = uicontrol('Style', 'pushbutton', 'String', 'Recalc',...
          'Position', [20 20 50 20],...
          'Callback', '@refreshdata');

Thanks in advance!!

Since a uitable does not have an 'XDataSource' etc. it will not update with refreshdata. You will need to write your own update function that updates the uitable based on whatever it is you are updating. If you can give us more info we can be able to help you through it.

Okay. And you said you want MATLAB to do something refreshing when that button is pushed. What do you want something do you want to be refreshed?

Hi I got a similar problem. I got my acceleration live plotting in a figure. After 10sec the plot ist over an with a pushbutton I want to run the program again without closing the figure. My code looks like this

if true
btn = uicontrol('Style', 'pushbutton', 'String', 'Clear',...
      'Position', [20 20 50 20],...
      'Callback', 'cla');
btn1 = uicontrol('Style', 'pushbutton', 'String', 'Start',...
      'Position', [20 0 50 20],...
      'Callback','newplot' );
  % code
end
