Gnuplot的图形跳转 [英] Gnuplot's Graphic Jump

问题描述

有没有一种方法可以避免在函数1/(2-x)中绘制近渐近线，例如，不使用进行条件绘制?想法是在此基础上绘制迭代函数，并且由于渐近线发生变化，因此使用条件绘图并不是一个好的解决方案.

is there a way to avoid the drawing of the near asymptote line in the function 1/(2-x), for example, without usage of conditional plotting? The idea is to draw iterated functions based in this one and, since asymptote changes, using conditional plotting isn't a good solution.

推荐答案

1. 您可以以很高的采样率绘制with points:

set yrange [-10:10]
set samples 100000
plot 1/(2-x) with points

1. 如果奇异性出现在不同的x值，则可以在y上使用条件绘图:

1. If the singularity occurs at different values of x you can use conditional plotting on y:

f(x)=1/(2-x)
set samples 1000
plot (abs(f(x)) < 10 ? f(x) : 1/0) with lines
