How can we make a boxplot like the one below for both x and y data (the box widths of each group that are x-data related are different). I tried boxplot(X,Y, group) but it did not work.

I missed that since BoxWidth is not mentioned on the documentation page for boxchart, however it is listed in the properties page.
Thanks, Benjamin.

The boxplot command creates a group of lines, so if you wanted to adjust the box widths you would need to manually adjust the XData properties on each line to move them to the desired locations.
The better alternative is to use the new boxchart command. The object created by the the boxchart command has a BoxWidth property, but I suspect you won't need it, because even when you specify x values, the boxes created by the boxchart command have uniform widths.
boxchart(randn(1000,1), 'BoxWidth', 0.3);
or
boxchart(randi(10,1000,1),randn(1000,1));

Thanks for the explanation, Benjamin.
I wonder what the logic is in converting numeric inputs to categorical under one syntax but not the other.
