Thank you for accepting the feature request and implementing the fix! I really appreciate it. This will make working with large datablocks much more practical.
Improvement of datablock size retrieval performance
Thank you for the explanation. It gave me a good understanding of how gnuplot has struggled to handle complex numbers since before IEEE 754 became widespread. The issue with Inf and NaN in Complex that I reported was actually a behavior I discovered while testing the display of complex numbers with the print command, as I was concerned about "Minor issue 2" (which had already been fixed). Therefore, this is a long-standing behavior and may not require immediate correction. I hope an optimal solution...
Inconsistent handling of complex numbers with infinity components
Enable 'smooth bezier' for 'with filledcurves between' style
Thanks for committing an improved implementation — much appreciated!
Handle split contour lines as one continuous curve
Thank you for the explanation. After applying the patch, I was able to set the border color for circles. By combining it with "set style fill", the interior of the circles can also be filled in the specified color. Looking at hidden3d.c, it seems that only the "circles" style is treated specially to allow set style fill to apply a fill style. I'm fully satisfied with this fix.
