Matlab strikes again with missing functionality for bode plots

Per usual I'm spending my weekends fighting with software that has the functionality of a ti89

I would like to have a sliding cursor on a bode plot so that i may locate a point at 180 degrees on the phase plot and have it go on the frequency plot also to define a gain margin. I have yet to be able to do this. So I'm assuming yet again matlab can't do this. I mean why would they? Every other single piece of simulation software on the planet allows you to at a minimum put a cursor on a set x or y point and find the value. We can't even do that math works? Your also going to tell me that for thousands and thousands of dollars the simulink data inspector has no functionality to make a bode plot? At least the data inspector has a sliding cursor. This is pretty sad considering what matlab costs

Try out the colorful buttons on the top toolbar of your figure window.

Click on the button shown by the big red box. This will bring up a + shaped cursor when you hover over the data line (the blue line, in this case). Click along the line to get a data point and its x,y values.

That is a data point! I need a full sliding cursor like every other program on the planet has including the data inspector in Simulink. Your wise guy response is null and void and you should be embarrassed for acting like a tuff guy without even fully understanding the questions!

I'm giving Robert a second chance by removing inappropriate language and flags. Robert, if you can't find a satisfactory solution or workaround here, then you can send your suggestions for enhancement to [e-mail].

[Robert]

Your giving me a second chance at what! Being harassed by someone that did not even read the question correctly and then replies with a wise guy reply? Remind me to thank you for that second chance to be harassed some more! Real good moderation! You wonder why this forum has such a terrible reputation this is WHY!

And by the way, the poster edited his post to make it sound less like a problem you never got to see his original!

Robert, if you encounter harassment here, please flag the message for attention and/or contact me or Star Strider (senior moderators from the community), or contact Rena Berman (MATLAB Central developer @ Mathworks) or Chen Lin (MATLAB Central product manager @ Mathworks), or contact [e-mail]

We do not permit personal attacks here, but we do permit opinions, so I have removed the inappropriate language from your posting and released it.

[Robert]

Excuse me? There was no inappropriate language and the comment was already moderated by "Image Analyst" You have no right to remove that post. There was nothing in that post that should cause it to be removed. Proof of that is such that "IMAGE ANALYST" did NOT remove it! Nor was there any inappropriate language.

You sir just like to hear the sound of your own voice and think you are the worlds gift from matlab. and per usual you are a day late and dollar short to the party. This Chaya person went back and edited his post to make himself not like as bad! His original post was ridiculous but per usual you missed it and don't care that he is the real problem here

I will contact math works and file a formal complaint against you

[Walter Roberson]

I am referring to your "Your giving me a second chance at what!" comment, which happened to trigger the anti-spam filters and so was held for approval. I removed some inappropriate language from what you said and released it to general view.

I did not see the original content of Chaya N's post, as I do not have the access to see past revisions of content, so I cannot comment on what Chaya N wrote. I gave you the information on how to contact the people who do have that access.

The volunteer moderators remove or edit out personal attacks and rudeness as they encounter them. We are mandated to do so:

Edit to address:
* Rudeness in content. Rewrite in a neutral tone.

MATLAB Answers is currently averaging over 130 new Questions every day, which is a bit slower than usual; it about a month it will reach over 210 new Questions every day. Sadly, the volunteers do not have the resources to read everything, and so rely upon people like you to bring questionable content to our attention.

Don't worry there Mr super cool moderator Ill be contacting math works on monday. I paid thousands of dollars to use this software and I'm entitled to my opinion and freedom of speech.

[Walter Roberson]

Robert, I am not sure which country you are in, but I know that in the United States, the First Amendment, commonly referred to as "Freedom of Speech", applies strictly to government action, not to commercial action.

Use of MATLAB Central is not subject to the First Amendment; instead it is covered by a Terms of Use http://www.mathworks.com/matlabcentral/termsofuse.html. As moderators, we rewrite or remove material that violates the Terms of Use.

Robert, an excellent way to avoid the problem of the response here being slower than you think is appropriate, is for you to step in and answer questions at the rapidity which you consider questions should be answered.

There are over 60000 unanswered questions, and new questions arrive at a rate of 100 to 270 per day, so we could use the assistance. I find that I can only get through 10 to 30 new answers a day (some of them take many hours of research; sometimes I have other things going on), so there plenty for everyone who cares to contribute.

Geoff Hayes posted a demo of similar functionality; see http://www.mathworks.com/matlabcentral/answers/295622-axes-with-moving-vertical-line#answer_229222
