gnuplot在绘图范围之外的点之间绘制线 [英] gnuplot draw line between points outside plot range

问题描述

以下内容在两点之间画了一条线:

The following draws a line between two points:

$myData<<EOD
10 0
20 10
EOD
plot $myData u 1:2 w l

只要两个点中的至少一个在x/yrange范围内，此方法就可以正常工作.但是，如果放大以使两个点都在轴范围之外，则会显示一个空图表:

This works fine as long as at least one of the two points is within the x/yrange. However, if you zoom in so that both points are outside the axes ranges, an empty chart is shown:

set yr[0:10]
set xr[12:18]

此行为与Excel仍然显示该行的行为不同.任何想法如何在gnuplot中做到这一点，即，即使点本身不在绘图范围之内，我也需要查看两个点之间的连接线.

This behavior is different from Excel which still shows the line. Any idea how to do this in gnuplot, i.e. I need to see the connecting lines between two points even if the points themselves are outside the plotting range.

推荐答案

使用该选项

set clip two

从文档中:

某些线的两个端点可能超出范围，但会穿过图形.设置两个clip-type可以绘制这些线的可见部分.

Some lines may have both endpoints out of range, but pass through the graph. Setting the two clip-type allows the visible portion of these lines to be drawn.
