Spline strange behaviour

[Joavn]

Hello i'm using spline in this chart and why it goes below "ground" for some reason.

In the attachment you have values i wanna display and how spline goes below 0.

Thanks in advance!

Hi Jovan,

I believe that this is expected result for such data. The spline will make a smooth transition and the actual point must be included in the line, this is why it goes below zero. You can adjust this with the SplineTension property but still, the line will go below zero. I have tested this in excel and I am getting the same results (see attached).

Let me know if you have additional questions.
