如何在图表中将普通文本和数学标签设置为 Helvetica？

Question

我需要知道为什么此图中的字符未全部设置为同一种字体。我希望所有文本都设置为 Helvetica，就像“cm”一样。

\documentclass[margin=10pt]{standalone}
\usepackage{tikz}

    % \usepackage{pgf,tikz}
    % \usetikzlibrary{arrows}
     \pagestyle{empty}
     \newcommand{\degre}{\ensuremath{^\circ}}
   \renewcommand{\rmdefault}{phv}





\definecolor{uququq}{rgb}{0.25098039215686274,0.25098039215686274,0.25098039215686274}

\draw [color=aqaqaq,fill=yellow,fill opacity=0.2, line width=2.1pt,dash pattern=on 12pt off 12pt] (4.0,-2.0)-- (-4.0,-2.0);



\draw[quote] (-4.0,-4.0) --
node[above] {\Large $85$ cm} (4.0,-4.0);


\begin{scriptsize}


%\draw[color=black] (-4,2.0) node {\textbf{\Huge\textbf{$+$}}};
