Hi @Greg
I am trying to sort the x-axis “Month short” ascending by “Month”. However, it doesn’t work specifically after adding max and min column marks.

Calling-out a specific forum member (or members) is discouraged. It may delay or prevent a response as many forum members will disregard such posts. Nevertheless, here’s what I came up with.
To resolve your sorting issue, move the X encoding into a shared encoding block outside the layer block, and use a max-month-ascending sort block. This fixes the bars, but messes-up the rule (as it now had x encoding), so I added a dedicated joinaggregate transform to calculate the mean and added a nested layer block.

Hope it helps.
