How to sort commit nodes chronologically

[Slartibartfast]

I know timestamps in Git are a somewhat fungible but is there a way to sort the commit nodes in SourceTree's graph chronologically as given by the date stamps.

I have two branches and frequently merge from the trunk into my feature branch and would like to see all these merges appear as rungs of a latter between the two branches.  For some reason though, the nodes are not listed chronologically and it makes an ungodly mess of lines:

According to the time stamps that yellow merge should have 'gone in' before the orange merge 'came out' and the orange should have 'gone in' before the blue 'came out' etc. and as a result the "tram lines" are 5 lanes wider than necessary. Is there a way to order by the time stamps as they are understood in the UI?

Arr, found the answer in this StackOverflow post: https://stackoverflow.com/questions/22878040/understanding-git-branches-graph-view/42262573#42262573

In particular I needed to sort by "Date Order" rather than "Ancestor Order" in that little bar at the top:

I had been trying to click the "Date" column and searching the "View" dropdown list in an attempt to get it to sort and didn't even realise that bar was there.
