Excel Line Chart Smoothing

Fri Mar 17, 2023 8:37 pm

Good Evening,

I am attempting to smooth the line on a line chart. I see multiple properties available on the ChartSerieDataFormat related to smoothing but all of them are marked as deprecated. The only property that is not, is the "IsSmoothed" property, but it is read-only. How am I meant to set the line to be smoothed? I am working with Spire.XLS version 12.7.1.0.

Thank you in advance!
