I’m working with small data sets (student grades over the year). The legacy smoothed time series used to return spline like functions that were perfect, but the modern smoothed time series is returning what look like Bezier curves that literally loop the loop and swing past points and back to them! I need to use the modern charts as only they allow you to turn off the grid. Does anyone have any suggestions please, and how could I request that the (original) spline be added as a styling in the modern charts? The feature request board seems to be underused. I don’t want to have to calculate my own splines because I am concerned about performance. Thank you!

Hi @Data_Coordinator Modern charts use a different smoothing method (Bezier-style), which can overshoot and create loops, especially with small datasets. There is currently no option to switch back to the legacy spline algorithm.
Your options are to disable smoothing for accurate lines, continue using legacy charts if spline behavior is critical, or submit a feature request via Help → Report a problem so it reaches the product team directly.
