Linestyle with plot3

Hi everyone,

how to change linestyle when using plot3. I am trying to plot a dashed dot line (-----) between two points, it is not working. When I used:

plot3([x1,x2],[y1,y2],[z1,z2],'linewidth',3,'k--'),

only the linewidth and the color change but the linestyle is still solid. Please, would someone explain me how to set changes. Thanks a lot for advance. All the best !!!

Look at the list of permitted syntaxes for plot3: the one you are using, with the linestyle following some name-value pairs is not listed. The one that Walter Roberson uses, where the linestyle precedes some name-value pairs is listed. You should always read the documentation.

plot3([x1,x2],[y1,y2],[z1,z2],'k--','linewidth',3),

Hi Roberson, I just tried it, it is the same, nothing is changing. I do not understand. Thank you !!!

It works for me. Which release are you using?

plot3([1 2],[3 4],[5 6],'k--','LineWidth',3)

Actually, I am not using matlab, I am using octave (GNU octave version 4.0.2). Maybe that is the cause of my issue. Because I just tried it again, same thing. What would you recommend to me then?

Octave support is described https://www.gnu.org/software/octave/support.html
