我遇到的问题是set xrange [2:200]情节发生变化并向上填充曲线，像这样，
我想知道如何使用默认范围和设置 xrange [2:20].
将填充保持在曲线下方，如第一个图中所示
"with filledcurves" 允许多种变体。请参阅 help filledcurves 的文档。默认值为 with filledcurves closed，它会尝试使用这些点来定义包围区域的周长。如果曲线超出图的边缘，则图的边缘用于完成周长。如您所见，有时程序选择的边不是您想要的边。
要控制它，请使用其他变体之一。在这种情况下，您可能需要 with filledcurves y=0，它将 y=0 处的线定义为周界的一部分。
