Plot points without connect it
显示 更早的评论
Hi
I have matrix A(20,100) and I want to plot first column with respect to second column but I do not want to connect the points together. I mean I just want to put these point on the graph I used
plot(A(:,1),A(:,2))
but this command connect points together
How I can do that?
Regards

scatter(A(:,1),A(:,2))

scatter() creates a single graphics handle. You can go ahead and legend() passing in multiple legend entries. For example,
plot(A(:,1), fitted_values);
hold on
scatter(A(:,1), A(:,2));
legend({'Fitted', 'Raw Data'})
Note: if you want different legends for different points you will need to use multiple scatter() calls.

plot(A(:,1),A(:,2), 'o')
or whatever marker you want to use

How do I make it possible to plot with lines conecting my dots with the plot() function?
I have tried using the 'r.-' marker, but it ONLY plots the dots on the figure.
assuming x and y are my data vectors
plot(x,y,".-r")

I always use hold and plot on top without a marker.
Example:
plot(x,y,".-r")
hold all;
plot(x,y)
