我正在尝试绘制特定形状的温度图。对于较少的元素（少于 3000），我没有问题，但对于过多的元素（超过 250k），我无法生成文件。从这些中，我希望大约 125k 个坐标可点击。我收到错误TeX capacity exceeded, sorry [token memory size=75830065].，并且该过程需要 10 多分钟。我正在使用 LuaLaTeX。
这是我当前的代码

temps001.dat 包含一个 251x1001 矩阵的数据，其中约 50% 为 nan 值。这是我的日志的一部分

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

我的电脑有 8GB 内存、Windows 7、core2quad。我已经尝试编辑由 打开的 lualatex.ini initexmf --edit-config-file=lualatex。它有：
main_memory=200000000000
pool_size=2000000000
save_size=2000000000
extra_mem_bot=2000000000
extra_mem_top=2000000000
font_mem_size=2000000000
一个好的解决方案是只让非 nan 值（约占所有这些坐标的 50%）可点击。这可能吗？最好停用捕捉到最近特征的功能。我只想在形状的任何地方显示温度。
编辑 1：我使用的是一台带有 g41 主板和 4gb ddr2 的计算机，处理器、硬盘和操作系统相同，有时，当机器什么都不做时（但不一定每次都不做时），代码就会编译。现在我让计算机恢复到当前配置，并且无法运行。
EDIT2：编辑后，lualatex.ini代码luatex.ini根本不运行，立即返回相同的错误。经过几次尝试后，它会尝试再次编译
