Hi, I have a P matrix from where I want to draw a figure with

open and closed dots for endpoints (piecewise step function). I tried following:

P=[0 2

1 4

2 6

3 8

4 10

5 12

6 14

7 16

8 18

9 20

10 22

];

figure

stairs(P(:,1),P(:,2))

If I use stairs function, then I get staircase plot. But I want open and closed dots for endpoints. Something like below:

[0, 1) 2

[1, 2) 4

[2, 3) 6

[3, 4) 8

[4, 5) 10

[5, 6) 12

[6, 7) 14

[7, 8) 16

[8,9) 18

[9,10) 20

[10,10] 22

Please see attahced figure. I am expecting something like this.

Can anyone please suggest me how to plot this piecewise step function?

Thanks in advance.

Hi,

You could refer to the below code:

 P=[0    2
1   4
2   6
3   8
4   10
5   12
6   14
7   16
8   18
9   20
10  22
];
for i=1:10
plot([P(i,1),P(i+1,1)],[P(i,2),P(i,2)],'b');
hold on;
h1=plot(P(i,1),P(i,2),'bo');
set(h1,'markerfacecolor',get(h1,'color'))
% plot([P(i+1,1),P(i+1,1)],[P(i,2),P(i+1,2)])
hold on;
plot(P(i+1,1),P(i,2),'bo')
hold on
end

Here, we break the single stairs function into parts and plot each line using plot function. Then, we plot blue circles on the respective points. Finally, we connect all the lines and obtain the final desired graph.
