如果有人可以帮助解决这个问题，我将不胜感激。我正在使用 gnuplot 5.0.0 处理雷达（或蜘蛛网）图：

在此处输入图像描述

所有轴的比例和范围都是相同的。1 和 1 以上的数字具有特殊含义，我想强调这一点。

我正在考虑三件可以提高知名度的事情：

  1. 只需将 1 处的刻度线（标记为“限制”）加粗。我怎么能只突出一个特定的刻度和标签？

  2. 我还可以突出显示第 1 层的圆形虚线

  3. 在绘图本身上，我希望半径 > 1 的背景颜色不同。

我怎样才能实现上述三个选项中的任何一个？当然，所有这三个都是理想的，但与该值的其余部分进行最小的区别会有所帮助。

这是在链接中生成图的原因：

我冒昧地简化了您的脚本，您现在可以轻松地调整网络中的臂数。还为 1 >r > M 添加了彩色背景。

顺便说一句，不需要在最后再次输入第一个数据点来关闭轮廓。更新：也就是说，不应该有。然而，最后一点和第一点之间的线丢失了，即使将“关闭”选项赋予“填充曲线”也是如此。我想知道这是否是一个错误。
