Tikz/PGF 图形中使用的字体

Question

我在 latex 文档中使用 Optima 字体。我想更改刻度标签的字体。

我尝试使用新的字体系列并设置 tikz 的全局选项，但它不起作用。

分数维：

\documentclass[oneside]{scrbook}

\usepackage{fontspec}
\usepackage[frenchmath]{newtxsf}
\setmainfont[Ligatures=TeX]{Optima}
\setmathrm{Optima}
\setmathsf{Optima}
\setmathtt{Optima}
\setboldmathrm[BoldFont={Optima ExtraBlack}]{Optima Bold}
\newfontfamily\Optima{Optima}
\usepackage[french]{babel}


%TIKZ PGF
\usepackage{tikz,tikzpagenodes,tkz-tab}
\usepackage{tikzsymbols}
\usetikzlibrary{backgrounds,shadows,matrix,arrows,arrows.meta,decorations.pathmorphing,shapes,plotmarks,shapes.geometric,decorations.markings,positioning,calc,shapes.misc,automata,cd,fit,datavisualization,datavisualization.formats.functions,patterns,ipe,decorations.shapes}
\usepackage{pgfornament}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepgfplotslibrary{groupplots}
\pgfplotsset{compat=1.11,every axis/.append style={
                    axis x line=middle,    % put the x axis in the middle
                    axis y line=middle,    % put the y axis in the middle
                    axis line style={<->}, % arrows on the axis
                    xlabel={$x$},          % default put x on x-axis
                    ylabel={$y$},          % default put y on y-axis
                    label style={font=\Optima},
                    tick label style={font=\Optima}  
                    }}
