# CTAN update: bezierplot

Date: July 24, 2018 11:05:22 AM CEST

Linus Romer submitted an update to the
bezierplot
package.
Version number: 1.2 2018-07-23
License type: lppl1.3c
Summary description: Approximate smooth function graphs with cubic bezier
splines for use with TikZ or MetaPost
Announcement text:

Changes: - new feature: ymin and ymax may be 'huge' (which is the numerical infinity in lua) - new feature: fixed samples may be set (if samples < 2, bezierplot chooses samples at the best points as usual) - the precision has been increased (more invisible samples, more digits) - more precise and faster computations for affine, quadratic, cubic functions and their inverses - no redundandt points after rounding anymore

The package's Catalogue entry can be viewed at http://www.ctan.org/pkg/bezierplot The package's files themselves can be inspected at http://mirror.ctan.org/macros/luatex/latex/bezierplot

Thanks for the upload. For the CTAN Team Erik Braun

## bezierplot – Approximate smooth function graphs with cubic bezier splines for use with TikZ or METAPOST

This package consists of a Lua program as well as
a (Lua)LaTeX `.sty` file.

Given a smooth function, `bezierplot` returns a smooth
bezier path written in TikZ notation (which also matches METAPOST)
that approximates the graph of the function.
For polynomial functions of degree ≤ 3 and their inverses
the approximation is exact (up to numeric precision).

`bezierplot` also finds special points such as
extreme points and inflection points and reduces the
number of used points.
