I have a 3D plot in a GUI showing position in 3 dimensions and want to display the points at which the velocity of the movement is zero. The line has already been plotted and the values for the targets have already been found but how do I add single points on to this figure?

Turn 'hold on', and then call plot3() to plot the points.

This didn't work, it was the first thing I tried.

What "didn't work" about it? Can you post your code?

在 MATLAB Online 中打开

You can use scatter3(), or you can use plot3() with a marker specifier and no line specifier

plot3(X(:), Y(:), Z(:), 'o')

Hi Walter,

I'm facing quite similar problems. I've tried the plot3 function, but when the marker are displayed, the current 3D plot will be gone. Note that I've already run hold on.
