Hi tcek, you have some ambition here, I have learnt a way to do so but it's a
little bit complicated, you may go here for some inspiration.. the author
shows how to do it for y-axis but similar applies for x-axis. Good luck!

I have a chart with x data that has many observations from 0 to 8 hours and a
single unit at 48 hours. I want to make the 0 to 8 data more visible. I
would prefer to have an axis that goes from 0 to 8 and then from 36 to 48.
How do I split/delete the 9 to 35 hour portion of the graph? Basically the x
axis would look somthing like: __________________//_______.
