How can i make a 2D text flash for 5 seconds while the myDAq detects data

   figure;
for i=0:1:5
    counter=0
    counter=0+i
    subplot(2,1,1)
    xlim([0 5])
    set(gca, 'Color', 'k')
    drawnow;
    text(0.5,2.5,'Measuring','Color','white','FontSize',12, 'TimeRange = 0..5')
    pause(.1)
     text(1,2.5,'Measuring','Color','black','FontSize',12)
    subplot(2,1,2)
    set(gca, 'Color', 'k')
    BPM=0;
    ti=0;
    FR=0;
    xlim([0 10])
    text(1,0.95,['BPM: ' BPM],'Color','white','FontSize',12)
    text(4.5,0.95,['P2P time: ' ti, 's'],'Color','white','FontSize',12)
    text(8,0.95,['Frequency: ' FR, 'Hz'],'Color','white','FontSize',12)    
   end

while the mydaq detects data, i want to display 'Measuring the RAW EMG signal' and the time left. the mydaq detects dats for 5 seconds. I want both the text and the timer to flash on the plot

You can record the handle of a text() object, and set the object Visible to 'on' or 'off' . After that you would pause() or drawnow() to update it.
