Hi,
I am having a matrix of time series of temperature images (lon,lat,time). The given images/matrix (see first attachment) starts from Africa/Europe and moves on to North/South America. My other data sets starts from North/South America and moves on to Africa/Europe See (second/third attachment). For further analysis I need to have same matrix or structure. How can I change the first image so that it looks like the second one. Maybe cropping the end and setting it in the front? Unfortunately, I am not able to do it.
Any help is appreciated! Thanks

Ok, so you can see that your image shows (from left to right) first africa than asia and lastly north/south america. I want to start it with N/S America than Africa than Asia like my last image (3rd or 4th)

ncfile = 'C:\Users\srinivas\Downloads\tmax.2016.nc' ;
lon = ncread(ncfile,'lon') ;
lat = ncread(ncfile,'lat') ;
tmax = ncread(ncfile,'tmax') ;
lon = lon-180 ;
idx = lon>=0 ;
lon(idx) = lon(idx)-360 ;
[lon,idx] = sort(lon) ;
pcolor(lon,lat,tmax(idx,:,1)') ; shading interp ;
