Creating a line with different steps

The idea is to plot some kind of staircase with sloped steps. I made this code, it runs but it doesn't plot a graph, any ideas what went wrong?

h=5

for x = [0.2:0.2:100]
    if x == [0.2:1:100] 
          y = h*x
    elseif x == [0.4:1:100]
          y= h*x
    elseif x == [0.6:1:100]
          y = h*x
    elseif x == [0.8:1:100]
          y= h*x - 0.2*h
    else  x == [1:1:100]
         y= h*x-0.4*h
end
end   
plot(x,y)

expected graph picture ?, you seem to be plotting a point, are you aware of stairs() ?

You can check the x and y value-

x =
    100.000000000000e+000
>> y
y =
    498.000000000000e+000

It's having single point, it just plot one point, that why not visible as line or graph.

From the statement

for x =[0.2:0.2:100] get last iteration value x=100 and from any one if else statement single y valie is assigned.

See the point

    plot(x,y,'*','linewidth',30);
    

Hope your doubt is cleared.

Yes but what is the remedy?

@Joyce You can do that in multiple ways, I have tried the way what you have tried so far. Please do the needful change as your required output.

x=[0:0.1:10];
h=2;
for i=1:length(x);
    if x(i)<1
    y(i)=h*x(i);
    elseif x(i)>=1 & x(i)<2
    y(i)=h*x(i)+3*h;
    elseif x(i)>=2 & x(i)<3
    y(i)=h*x(i)+4*h;
    elseif x(i)>=3 & x(i)<4
    y(i)=h*x(i)+5*h;
    else  
    y(i)=h*x(i)+6*h;
    end
end
plot(x,y)

You can change the shape of the curve (whether staircase or ramp) by changing the step and multiplication factor in 2nd part of expression 3*h. You can take the h as common and add constant value with x(i).. same thing.

Hope you get the idea and expecting it helps to way out from the issue.

Thanks and regards
