我有这个带有 const 图的 pgplot。想法是西北方向的第一个区域（实际上是背景）完全是绿色。然后第二个区域应该是蓝色，第三个区域应该是白色。如您所见，在使用背景色绿色填充蓝色区域时，有一些噪音……我不知道会发生什么。我将不胜感激任何帮助！
我在下面添加了图和我正在使用的代码。

答案1
您的代码在编译时确实会产生错误。还有其他错误，您可以从重新编译按钮旁边带有数字 13 的小红框中看到。如果出现错误，应始终进行修复（单击 13 以获取更多信息），否则您不能依赖输出。
;也就是说，你只是忘记在关闭}第一个图的坐标列表后删除，所以你有
}; %<--- this semicolon must be removed
\closedcycle;
删除分号，它似乎工作正常。
