我刚刚在 latexDraw 中制作了一个漂亮的图表，但我遇到的问题是似乎无法添加数学符号。
我猜这是因为配置，所以我查看是否可以修复它（见图）。
如果有帮助的话，我正在运行 xubuntu linux。
在首选项中，系统询问我二进制文件的位置，但我不知道它们在哪里。他们指的是 .sty 文件还是其他文件？这能解决问题吗？
更新：
我按照以下建议输入
>which latex
它又回来了
>/usr/bin/latex
所以我坚持这样做，但仍然有问题。此外，当我点击文件夹时，它转到了文件夹，usr/bin但它唯一能看到的文件夹是X11
产生的问题和代码的示例。

如果您使用的是 Linux，则无需设置 LaTeX 二进制文件的路径。此字段主要适用于 Windows 用户和自定义配置。
如果您遇到编译问题，则问题出在您必须包含在绘图中的 LaTeX 包。为此，您可以进入 LaTeX 选项卡中的首选项来设置用于所有绘图的包，或者使用 latexdraw 2.0.8 进入当前绘图的属性并设置用于当前绘图的包。使用 latexdraw 3.x 设置用于绘图的包，您必须单击文本按钮，然后工具栏将出现在应用程序底部。您可以在工具栏中设置包。
