How to make a Gui checkbox work

I am trying to make my check box for my gui either disp 'showHistory' or 'hideHistory' depending on whether the the box is checked I figured out how to make is so that when the box is checked that it is disp 'showHistory' but I dont know how to do the second part of this question. Here is my script so far:

figure;

first_button = uicontrol('style', 'pushbutton');

set(first_button, 'units', 'normalized', 'position', [0.2,0.7, 0.2, 0.2])

set(first_button, 'string', 'turn left')

set(first_button, 'callback', @turnLeft)

second_button = uicontrol('style', 'pushbutton');

set(second_button, 'units', 'normalized', 'position', [0.4, 0.7, 0.2, 0.2])

set(second_button, 'string', 'step')

set(second_button, 'callback', @step)

third_button = uicontrol('style', 'pushbutton');

set(third_button, 'units', 'normalized', 'position', [0.6, 0.7, 0.2, 0.2])

set(third_button, 'string', 'turn right')

set(third_button, 'callback', @turnRight)

fourth_button = uicontrol('style', 'pushbutton');

set(fourth_button, 'units', 'normalized', 'position', [0.2, 0.5, 0.2, 0.2])

set(fourth_button, 'string', 'left')

set(fourth_button, 'callback', @turnLeft)

fifth_button = uicontrol('style', 'pushbutton');

set(fifth_button, 'units', 'normalized', 'position', [0.4, 0.5, 0.2, 0.2])

set(fifth_button, 'string', 'back')

set(fifth_button, 'callback', @step)

sixth_button = uicontrol('style', 'pushbutton');

set(sixth_button, 'units', 'normalized', 'position', [0.6, 0.5, 0.2, 0.2])

set(sixth_button, 'string', 'right')

seventh_button = uicontrol ('Style','checkbox');

set(seventh_button, 'units', 'normalized', 'position', [0.2, 0.3, 0.2, 0.2])

set(seventh_button, 'string', 'History')

set(seventh_button, 'callback', @toggleHistory)

eighth_button = uicontrol ('style', 'edit');

set(eighth_button, 'units', 'normalized', 'position', [0.4, 0.37, 0.2, 0.05])

set(eighth_button, 'string', '2')

ninth_button = uicontrol('style','pushbutton');

set(ninth_button, 'units', 'normalized', 'position', [0.6, 0.3, 0.2, 0.2])

set(ninth_button, 'string', 'Run!')

function toggleHistory(sender, evendata)

disp('showHistory')

end

In the toggleHistory callback, use an if condition to check the value of the checkbox.

if sender.Value == 1
    disp showHistory
else
    disp hideHistory
end
