How do I add error bars to scatter plots?

I have a scatter plot and want to add error bars. The "errorbar" function is not giving me correct results. How do I do this?

The function "scatter" does not currently support error bars. However, these can be achieved by overlaying the results of "errorbar" on top of "scatter", like so:

>> x = [1,2,3];

>> y = x.^2;

>> scatter(x,y);

>> axis([0,4,0,10]);

>> hold on;

>> err = ones(size(x));

>> errorbar(x, y, err, 'LineStyle','none');

An enhancement request has been submitted for this feature so it will be considered for future releases of MATLAB.
