How can I generate a "histogram", which shows the relative frequencies depending on the angle as "vectors" in polar coordinates?

Hello!

I visualize my question in a short picture, which should help to understand my question.

I want a diagram, which shows the relative frequency of a property (depending on the angle) between 90° and 80° / 80° and 70° / 70° and 60° ...

It should be like a histogram, but the length of the "vector" represents the relative frequency and NOT the area of the "vector".

Thanks a lot!

This sounds like you want to use polarhistogram.

[Leo]

Thank you!

That is what i need!

[Leo]

How can I only see the area between 0 and 90 degree?

[Cris LaPierre]

Use thetalim.

Take a look at the polarhistogram function. You are likely going to want to set the 'Normalization' name-value pair argument to 'probability'.

[Leo]

Thank you for your answer! I know the normalization from the "normal" histogram.

I give Cris LaPierre the accepted answer, because he was earlier. Sorry!

[Steven Lord]

No need to apologize. Sometimes multiple people post good and/or correct answers more or less simultaneously. If you want to recognize other answers in addition to the one you accept you could vote for the others.

[Leo]

Yes, i give you a vote! Thank you! :)

I have another little question. Is it not possible to give label names for x and theta? With xlabel('...') the script runs, but it doesn´t show any text. With thetalabel('...') the script doen´t run anymore.

Where is my failure?

[Leo]

In short: I don´t know how to label the axes by this type of diagram.
