--- Comment #34 from Regina Henschel <rb.hensc...@t-online.de> --- That is no error in the implementation but a property of cubic splines. You see negative values and not being monotonic already with much smaller values. Try (0|1) (3|8) (6|64) (9|512) (12|4096) The site https://tools.timodenk.com/?p=cubic-spline-interpolation has an online calculator. Try it there and compare with LibreOffice. You get a more appealing result, when you use smaller x-distances if the y-differences change too rapidly otherwise. For 2^x for example (0|1) (5|32) (9|512) (11|2048) (12|4096) For me it is a resolve as "Not a bug". -- You are receiving this mail because: You are the assignee for the bug.
