Charticulaotr add vertical line to line chart and ...

Hi all,

Beginner to charticulator and trying to see what is possible with regards to customizing a line chart. Below I have the following chart which is used to track points within a tennis match:

As you can see, the x-axis starts at -1 on the y-axis, but ideally i need this to always start at 0. Is this possible?

Also, as the match progresses the players will be playing in different sets. I would like to include a vertical line to show when a new set starts. Within the data there will be a column that details set score, and when this change from set 1 to set 2, for example, I would like a vertical line for the first instance of when it is set 2 (or set 3 or set 4 or set 5).

Hope this makes sense, and any help or guidance would be much appreciated.
