Hi Simon

Depends on how you have created your XY chart. If you have an array of clusters see the attached diagram, if you have a cluster of arrays then just extract the Y array from the cluster and find the Max Y in a similar way to the diagram.

Hope this helps

Hi,

you have different way to build an XY graph (multi/single plot, etc) depending on this, the way to proceed will be slightly different.
but to access the whole data in the graph at the end, you can use a local variable and unbundle plot by plot to get the array that correspond to each Y plot, then use the "Array Max & Min" function in the array palette.

If you need further help, post your VI 😉

Hope this helps
