Hi

I plot a scatter for multiple points and i want to connect them using line. Below is my code. The plot i get is only scatter, I cant connect them through a line. Any help appreciated!

x=[1,2,3,4,5,6,7,8,9];

y=[1,2,3,4,5,6,7,8,9];

hold all

for i=1:8

scatter(x(i),y(i),'X')

line(x(i),y(i))

end

Thanks

Matt

If you want to plot both markers and a line, you can use the plot function and specify a line style that includes marker symbols and a line style, such as '-x'. For example, this code plots a line with crosses at the data points.

plot(x,y,'-x')

If you are trying to plot only the first eight points, then use this code instead:

plot(x(1:8),y(1:8),'-x')

If you are plotting from a cell array, then use this code instead:

plot(cell2mat(x(1:8)),cell2mat(y(1:8)),'-x')

Great! You can accept John's answer as I kind of use his to answer your question. Glad it helped!

You asked this question before! In fact, you asked exactly that question, but for some reason nobody managed to give a good answer.

plot(x(1:8),y(1:8),'b-x')

There is NO need for a loop. The above single line will plot x marks at each point, and connect them with a line, all in blue.

If you prefer to plot the line in blue, and the x marks in red, this will do it:

plot(x(1:8),y(1:8),'b-',x(1:8),y(1:8),'rx')

@ZETT: This is a TOTALLY different question. Ask it as a question. A separate and new question.

Don't use a for loop:

x=[1,2,3,4,5,6,7,8,9];

y=[1,2,3,4,5,6,7,8,9];

hold on

scatter(x,y,'X')

line(x,y)

or just

plot(x,y,'-o')

Both of you have missed that for some reason, he wants to plot the first 8 elements.
