How to change the distance between the bars in a bar graph

I have made this bar graph

x = [-3,0,2,4,7,10,12]
y = [1,1,0,1,3,3,2]
bar(x,y)

When I run the script it shows me the bar graph but the distance between the bars are not equal. How do I set them to be equal?

In your above code, you are creating bars of height y (height 1 for first bar, 1 for second bar, 0 for third bar, and so on...) with the bars centered around the values in x (first bar centered at -3, second bar centered at 0, etc).

If you want to have equal spacing between bars, then create an x that has equal spacing between elements.

If you need x to be spaced between specific values then look into the linspace command.

Otherwise, simply typing

y = [1,1,0,1,3,3,2]
bar(y)

will produce equally spaced bars.

% x = [-3,0,2,4,7,10,12]
y = [1,1,0,1,3,3,2] ;
dist = 1 ;    % give the distance you want >0
x = 1:dist:(1+(length(y)-1)*dist) ;
bar(x,y)
