So I want to make a plot of PWM ,how ever the plot commant make it wrong becouse it conects the dots in the wrong places . for exmaple , I want to make PWM of 10 Hz when the duty cycle is 60% . so this is the code :
clc;clear all;
for i=1:10
as you can see in figure 2 the stem plot 0-6 I get ones and after 7 it all zeors :
and when I use regular plot insted of stem there is diaganole between 6 and 7,the question how can I make it like the stem plot but continuous ?

I'm having trouble visualizing what you're describing. What would the continuous step plot look like?

If I understand correctly, you want the "plot" command to produce a vertical "line" at x=6. To do this, you could duplicate the x-variable at value 6, and make it double-valued in the y variable:
x = [1:6,6:10]
y = ones(size(x))
y(7:end) = 0
Is this what you are looking for?

Note that this solution will only work with this exact input vector.

If a step function is what you're looking for, this single line below will calculate the x values for any vector of 1s and 0s.
x = cumsum([0,diff(vector_ones)]==0);
plot(x,vector_ones, 'r-')
ylim([-1 2])
grid on
