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):
without wind_rose comand it works normaly: https://docs.google.com/open?id=0B51ZU50t_ZgXd1FwS2pBSlpRS1dCNkFwVHlCd3ZoUQ
How to get that? Please help!

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

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)

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.
