How to find maximum value in struct array

I have a struct that looks something like this:

data.index
data.x
data.y

It has anywhere from 1 to 100 elements that I can access with data(Window_Size).y (or whatever). What I want to do is compare all x values and all y values, independently, to get the maxX, maxY, minX, and minY.

I tried something like this

MaxX = max(data(:).x);

but that doesn't seem to work. Any help would be appreciated; I have absolutely zero experience with Matlab beyond the past few hours trying to figure this out.

You’re almost there! Try this:

MaxX = max([data.x]);

data.x is a comma-separated list of all values in the x field. The [] concatenates them into a row array, sort of the same as [data(1).x, data(2).x, ...].
