如何恢复丢失的子刻度线和丢失的刻度标签？

Question

我尝试设置一个具有精确指定子刻度的绘图区域。

不幸的是，尽管我已精确指定填充为单个子刻度宽度的整数倍，但有时靠近边缘的子刻度线和刻度标签仍会丢失。

如何解决这个问题？

最后一条右侧垂直线未使用 \psaxes 绘制，以便让箭头在“刻度”线的右侧结束。如果您需要此线，请尝试\psgrid。但是（需要包pst-calculate：

\psaxes[dx=\dx,
        dy=\dy,
        labels=none,
        xticksize=-\AxisT\space \AxisT,
        yticksize=\AxisL\space \pscalculate{\XMax+\dx/3},
        subticksize=1,
        subtickcolor=Red!50,
        tickcolor=Green!50](0,0)(\AxisL,\AxisB)(\AxisR,\AxisT)
