[How do I eliminate these steps and make all curves continuous?]

hi Juan.

thanks for your answer.

It is a very large application and difficult to replicate.

This next screen is the same data presented by a previous compilation of the source code.

Note: No source lines for the graphic parts have been changed.

But inexplicably the lines started to appear without interpolation following a zero order holder pattern.

what property controls this?

 

I tried using this.

chart1.Series.Gallery = Gallery.Lines;

My application creates the graphics curves in the same way but
some curves have steps and others show interpolated curves.

How do I eliminate these steps and make all curves continuous. ?
