MATLAB: Changing Data Marker Display Information

data markernyquist

Hey guys! I'm trying to analyze a Nyquist diagram curve and when I right click on the curve with the data cursor, an X Y point is returned. I need the data marker to display the information contained in the second image. I feel like there is a setting I need to change; I'm pretty new to Matlab so I apologize if this is a stupid question!

I haven't worked with diagrams like this, I think if you use nyquist, you might get a datatip that looks like on the second picture. https://www.mathworks.com/help/ident/ref/nyquist.html

Otherwise, take a look here and here.

You can post a comment to the Question reminding people about the question. Common comments in such cases include "Does anyone have any ideas" and "Bump".

You can, as Greg suggests, try the newsgroup, or another resource such as stackedgen

Your QPSK question is a communications theory question rather than a MATLAB question, so you should have posted it somewhere that discusses communications theory, or find some local resource (e.g., a university) where people know something about communications theory.

Beyond that, it becomes time to hire a consultant (or possibly tutor), if you can find one. Mathworks does offer a consultancy program.

As a general statement (not directed at you in particular): one of the best ways to get a good response is to ask better questions

MATLAB: How to change the data cursor size, colour and shape

You can change the properties of Data Cursor using the following commands:

set(alldatacursors,'FontSize',12);
set(alldatacursors,'FontName','Times');
set(alldatacursors, 'FontWeight', 'bold');
