避免在 xticklabels 中重复 \num / 其他命令

我创建了以下图像，对此我非常满意

在此处输入图片描述

由于不断遇到溢出错误，我不得不缩减函数。我对代码很满意，但

   yticklabels = {0,\num{20000}, \num{40000}, \num{60000}, \num{80000}, \num{100000},%
                   \num{120000},\num{140000},\num{160000},\num{180000},\num{200000}},

部分。这能以某种方式实现自动化吗，也许使用for-loop？

添加\usepackage{xfp}并使用yticklabel = {\num{\fpeval{\tick*10000}}}。
