Plot on top of semilogy plot

Hello, thanks for reading this,

I want to make a plot on top of a semilogy plot. What I mean by this is the following:

I have a test row array:

    B = [236715  13924  3292  2158  1450  971  977  1180  1117  360]

and I create a semilogy plot with the command:

    semilogy(B, '*-')

Now, just for some look-pretty visualization, I want to add something on top of this: lines coming from each of the points down to the x axis. Using the major gridlines isn't what I mean, I mean plotting on top of this lines from each of the 10 points back down to the x axis (coloring will change depending on parameters).

I use the code listed here:

    for i=1:10
        hold on
        line([i i],[B(i) 0], 'r')
    end

to make the lines, but it doesn't show up. I can make hold on plots just using individual points, but any kind of traced line I try to create doesn't work. I tried using this code with the plot of B, instead of the semilogy plot, and it works, but the data doesn't look as good. Is there a way to trace on top of this?

Thanks!

Try the stem plot function:

B = [236715  13924  3292  2158  1450  971  977  1180  1117  360];
L = length(B);

figure(1)
semilogy(B, '*-')
hold on
stem(1:L, B, 'r')
hold off
