I have a graph builder output that looks like the one below and as you can see, it is WAAAYYY too congested.
The code I used to generate such a plot is in attachment where I had to use 3 graph elements per graph side (week vs month):
line, points (mean), and bar (for the values but the bars are set to be entirely transparents and white).
If there is another way to force labels, I was not able to figure that out.
That said, I can't get label format or offset to work either. I tried both at the end of my graph buidler to send it messages and I tried including the label stuff in my bar section of the elements. Can someone please help me?

Instead of adding graph labels, you could edit the axis settings:

Steps:
- Double-click the Y Axis
- Change the Maximum to 1.0
- Change the Increment to 0.1
- Click OK
This will make the values clearer without data labels.
