如何跳过 tkzAxe 上的刻度标签？

Question

下图显示了我的问题：我想跳过 x_2 轴上的“2”。我该怎么做？

相应的代码如下：

\documentclass[11pt,a4paper]{article}
\usepackage{tkz-euclide}
\usetkzobj{all}

\pgfdeclarepatternformonly{myDots}{\pgfqpoint{-1pt}{-1pt}}{\pgfqpoint{1pt}{1pt}}{\pgfqpoint{10pt}{10pt}}%
{
    \pgfpathcircle{\pgfqpoint{0pt}{0pt}}{.5pt}
    \pgfusepath{fill}
}

\begin{document}
    \begin{tikzpicture}
        \tkzInit[xmin=-2,xmax=4,ymin=0,ymax=5]
        \tkzAxeX[label=$x_1$]
        \tkzAxeY[label=$x_2$,orig=false]

        % points
        \tkzDefPoint(0,0){x1}   
        \tkzDefPoint(0,3){x2}
        \tkzDefPoint(3,3){x3}
        \tkzDefPoint(2,0){x4}

        {
            \tkzSetUpPoint[size=10,fill=black]
            \tkzDrawPoints(x1,x2,x3,x4)
        }

        % decision space
        \tkzDrawSegments(x2,x3 x4,x3)
        \tkzFillPolygon[pattern=myDots](x1,x2,x3,x4)
        \tkzDefPoint(1.,1.75){X}  
        \tkzLabelPoint(X){$\mathcal{X}$}

        % D-set 
        \tkzDefPoint(0,1.75){p1}
        \tkzLabelPoint[right](p1){$x'$}
        \tkzDefPoint(-1.5,2.25){p2}
        \tkzDefPoint(-0.75,3.75){p3}

        \tkzDrawSegments(p2,p1 p1,p3)

        \tkzDefPoint(-1,3){d1}
        \tkzLabelPoint[left](d1){$\mathcal{D}_{x'}$}
        \tkzFillPolygon[pattern=dots](p1,p2,p3) 
    \end{tikzpicture}
\end{document}

先感谢您！

这是一个解决方案，使用\tkzDrawY和\tkzLabelPoint命令。

笔记可以使用\tkzDefPoint

\documentclass[11pt,a4paper]{article}
\usepackage{tkz-euclide}
\usetkzobj{all}

\pgfdeclarepatternformonly{myDots}{\pgfqpoint{-1pt}{-1pt}}{\pgfqpoint{1pt}{1pt}}{\pgfqpoint{10pt}{10pt}}%
{
    \pgfpathcircle{\pgfqpoint{0pt}{0pt}}{.5pt}
    \pgfusepath{fill}
}

\begin{document}
    \begin{tikzpicture}
        \tkzInit[xmin=-2,xmax=4,ymin=0,ymax=5]
        \tkzAxeX[label=$x_1$]
        \tkzDrawY[label=$x_2$]
        \foreach \y in {1,...,5} {% 
        \ifnum \y=2
        %\tkzLabelPoint[right=1pt](0,\y){\y} 
        \else
        \tkzLabelPoint[left=1pt](0,\y){\y}
        \fi}

        % points
        \tkzDefPoint(0,0){x1}   
        \tkzDefPoint(0,3){x2}
        \tkzDefPoint(3,3){x3}
        \tkzDefPoint(2,0){x4}

        {
            \tkzSetUpPoint[size=10,fill=black]
            \tkzDrawPoints(x1,x2,x3,x4)
        }

        % decision space
        \tkzDrawSegments(x2,x3 x4,x3)
        \tkzFillPolygon[pattern=myDots](x1,x2,x3,x4)
        \tkzDefPoint(1.,1.75){X}  
        \tkzLabelPoint(X){$\mathcal{X}$}

        % D-set 
        \tkzDefPoint(0,1.75){p1}
        \tkzLabelPoint[right](p1){$x'$}
        \tkzDefPoint(-1.5,2.25){p2}
        \tkzDefPoint(-0.75,3.75){p3}

        \tkzDrawSegments(p2,p1 p1,p3)

        \tkzDefPoint(-1,3){d1}
        \tkzLabelPoint[left](d1){$\mathcal{D}_{x'}$}
        \tkzFillPolygon[pattern=dots](p1,p2,p3) 
    \end{tikzpicture}
\end{document}
