SplineSeries overshot in some Charts

I'm creating a tool for showing measured data from a database.

Sometimes the SplineSeries of some measures overshoot a lot. Is there anything I can adjust to get another SplineSeries or maybe even a least squares method?

I made some screenshots and the example data to show what I mean... I'm just adding the data in the file attached to this thread to a SplineSeries.

I hope you can help me :-)

Thank you ver much!

Hi Victor, 
Thanks for contacting Syncfusion Support. 
Currently we have rendered SplineSeries of SfChart with natural spline curve logic. So, that some curve points are overshot. 
However, we can attain your requirement by rendering the SplineSeries with monotonic curve instead of natural curve.We have considered this requirement as feature enhancement and it will be available in any of our upcoming releases.
