Homebrewとgunplotのインストール

Homebreのインストールをしてgnuplotを使いたいのですが、Homebrewをインストールした後にgnuplotをインストールし、起動しようとしてもcommand not foundと出ます。
試しにbrew doctorと打ち込んだところ

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /Users/[]/opt/anaconda3/bin/icu-config
  /Users/[]/opt/anaconda3/bin/krb5-config
  /Users/[]/opt/anaconda3/bin/freetype-config
  /Users/[]/opt/anaconda3/bin/xslt-config
  /Users/[]/opt/anaconda3/bin/libpng16-config
  /Users/[]/opt/anaconda3/bin/libpng-config
  /Users/[]/opt/anaconda3/bin/xml2-config
  /Users/[]/opt/anaconda3/bin/python3-config
  /Users/[]/opt/anaconda3/bin/curl-config
  /Users/[]/opt/anaconda3/bin/ncursesw6-config
  /Users/[]/opt/anaconda3/bin/pcre-config
  /Users/[]/opt/anaconda3/bin/python3.8-config

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause formulae that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
