MATLAB: Plotting error bars in both x and y data

different error dat in x and y

Hi, i want to plot data set x vs y. Now i have different error values in x and y. I want to plot error in both planes. The command error bar plots same error either horizontally, vertically or in both directions. But i want to plot different sets of errors in x and y. how can i do that. many thanks for your help.

I am not certain what the problem is.

I am not certain what you want as a result.

The scatter function is an option:

figure
scatter(x, y, err_x*100)
grid

If you want to plot the errors as ellipses:

a = linspace(0, 2*pi, 10);
elps = [cos(a); sin(a)];
for k = 1:numel(x)
    mrkrs(:,:,k) = [err_x(k).*elps(1,:)+x(k); err_y(k).*elps(2,:)+y(k)];
end
    
figure
scatter(x, y, '+')
hold all
for k = 1:size(mrkrs,3)
    plot(mrkrs(1,:,k), mrkrs(2,:,k))
end
hold off
grid
axis equal

Experiment to get the result you want.

MATLAB: Plotting error bars / Standdarddeviations

You did not say exactly what you had tried.

See if this does what you want:

figure
errorbar(x, y, err)
grid
xlim([0  15]);

The error bars will be symmetric, and ± the standard deviations at each point.
