Visualization of standard deviation in scatter plot
13 views (last 30 days)
I have a 2-d scatter plot in Matlab. Let's assume the following scatter plot:
x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
For each point in this plot I have a standard deviation in x and y direction. Now I would like to visualize the standard deviations of each point. A possibility would be to draw a circle (or rectangle) around each point. The problem is that I have many points and the circle / rectangles would highly overlap.
What are the best solutions for this visualization?
