Bezier-Kurve
To smooth out the empirical data, I tried using the Bezier curve. The link to the program is given below. But I don't like breaking the smoothness of the Bezier curve at the 4th point. As far as I understand, there should not be such a sharp break in the Bezier curve. Can someone tell me where and what I'm wrong about? The program's executable module, prg file, and Excel file with the source data can be downloaded from my site at the link: http://lc.kubagro.ru/Bezier.zip

hi,
Offtopic : please rename Sheetname to English add this into your Code
else 3-PP Software might have Problem to open Sheet

for your Problem with Math Question to display Graphic xBase is wrong Language.
you can try to find Math Solution for Excel but most it have to do with Business
have a Look at MathLab https://www.mathworks.com/products/matlab.html
this Software is for Scientists ... but it is "C"

Points where the Bezier curve is incorrect are circled in red

as i can say : you use wrong Scale
i guess you need to calculate more Points between to get it smooth.
i found some Excel Sample like this it use Excel to calculate 10 Point between and to paint Chart

there are 3-PP Solution to Read/Write Excel XLSx without Excel.
you can include Formula and Image. the Problem are calculation and Macro which are use in this Sample.
to do it with Xbase++ seems me wrong Way ... it take too much Time.
for Math Problem with many Data it is wrong Software

Re: Bezier-Kurve
When there are a lot of points, this also works incorrectly, but the errors are not visible to the eye
