Does anyone know what the scripts in the /private directory are for and why it's named as such? Private directories are not allowed in the Matlab path, so how are the scripts in this directory to be used? Thanks for your help - seems like a great program so far.

Please read my comment above. I had the same problem, but finally I could solve it!

Thanks,

Everything is working great but when I print the plot (either to paper or to a jpeg file), the background turns black. Do you know how to fix this?

Thanks! Victoria

It's beautiful, but I would also like to know how to plot the wind rose on a subplot.

niice!

very helpful. nicely implemented.

please what kind of data is the argument F needed by the function WIND_ROSE(D,F,VARAGIN) ?

This is the first time i have downloaded and installed ncx on a windows xp machine with matlab R2007a. After typing nxc it displays the GUI, but upon loading a file the following error message comes up. any help?
>> ncx

There is a problem when you want to print the graphic. The
background color (facecolor) is set in black and cannot be changed.

In order to fix it, write at the end of the code:

set(gcf,'color','w');
set(gca,'color','w');

Thanks and good job.

M.

this is a very useful tool , thanks for your share.ı created cube vertices and faces and patched this .After that I made up a line crossing this cube in two points. And used this tool.Meetpoint showed three same points and missed the point crossed the cube behind. Why is that ?

Hello MMA,
Great m-file. However I am not a matlab expert and cannot get the legend right in my figure. Do you maybe have the example input of the figure that is shown on the top of this file, so that I can make slight changes towards my own case?

Dear D S: you should write this kind of quenstions on the Newsreader (where many people will be glad to help you) or write directly to the author. Look at 5 statements here below. Carlos

Very Good! But I don't know how to use 'di', who can help me please? Thanks!

Good, however it seems that the northern bin may have a bug. If I want 22.5 degree bins (nAngles=16), then the first bin is -11.25 to +11.25 (which is good). But the Ay breakdown and input data is from 0 to 360 (i.e., nothing from -11.25 to 0). So the northern bin is usually about half the size it should be.

This is a great ap that I find I am using all the time now for plotting and animating vector fields. It looks great!

Is there a way to show when there is no wind? Calm times should be included in the percentages, but it looks like there is no way to do this with the current code. Any suggestions?

very good job!!!

Great work! Thank you!

G L. You are not right, the convertion is mod(-90-D,360). But anyway this utility has nothing to do about wind!! Or conventions !! The convertions to meteo convention was introduced because some people asked it!. Believe me, there are others conventions on directions of other fields. This is an Intensity/Frequency/Direction Plot! It has NOTHING to do about wind. So anybody can convert any direction to any other direction and and use wind_rose with standard direction.

Many thanks. Nice routine, but I must add my voice to others here. The conversion from meteo to cartesian should be new_dir = mod(90-test_dir,360) as meteo convention is wind direction FROM and cartesian is vector directed TO. I would have thought that the simple test
D=270
V=1
wind_rose(D,V,'dtype','meteo')
should result in a single bar COMING FROM the west. In the present routine it does not. It is a simple fix to correct this behaviour, as previously pointed out.

Thanks again.

You are right Wu. The bug is now fixed.
Thank you

I suggest you to read the help of this function. Notice the dtype varargin option:

"-dtype, type of input directions D, standard or meteo, if meteo, the conversion dnew=mod(-90-D,360) is done; if not meteo, standard is used (default)"

I have been thinking about switching to another tool for contour plots, but this neat script saved me! Thank you.

The plots look great.

I originally had trouble getting the wind angles to turn out correctly - my inputs have 0 = wind from North, 90 = wind from East, etc.

I did some testing and found that if I did new_dir = mod(90-test_dir,360) (NOT -90!) and then did the standard wind rose, it came out right.
