can not subplot wind rose

I have to plot 3 pictures on one sheet, I do:

subplot(1,3,1)
contourf(piture 1)
subplot(1,3,2)
contourf(piture 2)
subplot(1,3,3)
wind_rose(dir,spd)

But result is wrong (like Matlab does not understand the 3-rd subplot and plots it separated on above the other subplots):

https://docs.google.com/open?id=0B51ZU50t_ZgXTjVINzdDV1BTd0t6d2lWX3IxWjV3dw

without wind_rose comand it works normaly: https://docs.google.com/open?id=0B51ZU50t_ZgXd1FwS2pBSlpRS1dCNkFwVHlCd3ZoUQ

But I need: https://docs.google.com/open?id=0B51ZU50t_ZgXUC01a19MZC1TSWFRY0gxeGZkODZSdw

How to get that? Please help!

What is wind_rose? Does it specify an axes somewhere in its first few lines?

wind_rose appears to be http://www.mathworks.com/matlabcentral/fileexchange/17748-windrose

The documentation for which says,

        -ax, to place wind rose on pervious axes, the input for ax
             must be [theax x y width], where theax is the previous
             axes, x and y are the location and width is the wind
             rose width relative to theax width (default=1/5)
        -parent, by default a new axes is created unless parent is
                 given, ex, parent may be a subplot

This suggests to me that the appropriate call Zach wants would be

wind_rose(dir,spd, '-parent', gca)

[Sean de Wolski]

or ...'parent',subplot(1,3,3))

[Zach]

Thank you!

wind_rose(dir,spd, 'parent', subplot(1,3,3))

works good! the result is: https://docs.google.com/open?id=0B51ZU50t_ZgXTHVPMGJSTnRSQ2VBUmt4eTJFMVlfQQ

P.S.

How could I enlarge all 3 subplots and make less distance between subplots?

[Sean de Wolski]

Change their 'position' and 'outerposition' property

This parameter: 'parent', subplot(1,3,3) --> it work perfectly in Matlab version 2013, but not in version 2015. Does anyone know if they have another method? This a message error:

_"Conversion to logical from matlab.graphics.axis.Axes is not possible.

Error in wind_rose (line 250) if parent"_

Thanks!!

[Walter Roberson]

In the code for wind_row change

if parent

to

if parent ~= 0

[João Paulo Ferreira]

Perfect Walter!

Thank you very much!

Walter, is it possible to record the rose in .PNG with the white background to transparent? I usually record the figure with the command below, but I do not know how to leave the background transparent.

set(gcf,'PaperUnits','centimeters','PaperPosition',[0 0 30 20]); % A4 maximized landscape
print('-dpng',fullfile(fname,filename),'-r300'); % 300 are the DPI

Thanks if you can help.

If I recall, export_fig from the File Exchange can handle transparency in PNG. This corresponds logically to doing a screen grab of the figure and setting the Alpha or the Transparency https://www.mathworks.com/help/matlab/ref/imwrite.html#input_argument_d0e485690 properties . You can thus do the same thing by using

cdata = print('-RGBImage', '-r300');

and then imwrite() cdata to the file specifying 'Transparency' and the RGB value of the background color you wish to make transparent.
