我是靠谱客的博主任性大碗，最近开发中收集的这篇文章主要介绍matlab画十字标记,为什么matlab中ginput函数的十字基准点会擦除原图，觉得挺不错的，现在分享给大家，希望可以做个参考。

Question: Using ginput(1) on surf(peaks) in

Matlab R2013a leads to the fact, that the drawn crosshair erases

the underlying plot. Seems like the redraw-command is not invoked.

Is this a known bug, is there anything I'm doing wrong or does

anyone know a workaround?

Thanks a lot for your help!

Answer:

try updating your graphics drivers. If that does not work, run the

following:

opengl software

to force MATLAB to use the software implementation of OpenGL
