MATLAB图:奇怪的水平线 [英] MATLAB plot: strange horizontal lines

问题描述

我正在尝试绘制theta与omega的曲线图(x轴为theta，y轴为ω)，除了似乎偏离-pi的水平线外，我生成的图看起来还可以到pi.有谁知道是什么原因导致这种情况发生，或如何将其删除?

I am trying to produce a plot of theta vs. omega (theta on the x-axis, omega on the y-axis) and the plot I am generating looks ok except for stray horizontal lines that seem to span from -pi to pi. Does anyone know what causes this to happen, or how to remove them?

谢谢

推荐答案

除非您提供代码，否则我们将无法提供良好的答案.这些方法可能会有所帮助，但是:

Unless you provide your code, we won't be able to provide the good answer. These methods might help, though:

• 如果绘图上有足够的点，并且在绘图中它们很密集，而在不需要的线上则较不密集，则可以尝试将'bx'插入到plot中，因此该图形将仅包含可能会使看不见的线保留剩余的图形.
• 您可以手动或通过添加诸如A(A>2)=NaN之类的命令将矩阵中所有不需要的点转换为NaN.

• If there are sufficient points on the plot, and they are dense in the plot and less dense on the unwanted lines, you can try to insert 'bx' into plot, so the graph would consist of only blue crosses that would possibly make lines invisible retaining the remaining graph.
• You can convert all the unwanted points in the matrices to NaN either manually or by adding some command like A(A>2)=NaN.
