处理大数字 pstricks

我正在尝试绘制一些函数，为此我使用 Geogebra 生成图形，以下是生成的代码。

但是当我尝试编译时出现以下错误

Illegal unit of measure (pt inserted).
<to be read again> E
l.6 ...)(1.1007960524213434E10,44.984471028928745)

我做错了什么？非常感谢...

答案1

使用

\psdot(! 1.1007960524213434E10 44.984471028928745)

然后它将被读取为 PostScript 坐标。但是，对于环境pspicture和宏，\psplot您必须更改坐标。但是从 Geogebra 导出完全无法使用！
