Hi,
I am trying to plot a timeseries data of the SST at certain locations on the world but I keep getting a blank plot. This is my code:
load global_sstfigureimagescn(lon,lat,mean(sst,3))hold ongomlon = [21.25 1.25 -18.75 111.25 -116.25 176.25 -91.25 136.25];gomlat = [26.25 11.25 -13.75 61.25 16.25 31.25 -76.25 -23.75];plot(gomlon,gomlat,'ro')text(21.25 ,26.25,'1','color','red','horiz','center','vert','bot');text(1.25 ,11.25,'2','color','red','horiz','center','vert','bot');text(-18.75 ,-13.75,'3','color','red','horiz','center','vert','bot');text(111.25 ,61.25,'4','color','red','horiz','center','vert','bot');text(-116.25 ,16.25,'5','color','red','horiz','center','vert','bot');text(176.25 ,31.25,'6','color','red','horiz','center','vert','bot');text(-91.25 ,-76.25,'7','color','red','horiz','center','vert','bot');text(136.25 ,-23.75,'8','color','red','horiz','center','vert','bot');%% Location 1
gomlon1 = [18.75 18.75 23.75 23.75];gomlat1 = [28.75 23.75 28.75 23.75];[Lon,Lat] = meshgrid(lon,lat);mask1 = geomask(Lat,Lon,gomlat1,gomlon1);contour(Lon,Lat,double(mask1),[0.5 0.5],'b')%% Location 2
gomlon2 = [3.75 3.75 -1.25 -1.25];gomlat2 = [13.75 8.75 13.75 8.75];[Lon,Lat] = meshgrid(lon,lat);mask2 = geomask(Lat,Lon,gomlat2,gomlon2);contour(Lon,Lat,double(mask2),[0.5 0.5],'b')%% Location 3

gomlon5 = [-118.75 -118.75 -113.75 -113.75];gomlat5 = [18.75 13.75 18.75 13.75];[Lon,Lat] = meshgrid(lon,lat);mask5 = geomask(Lat,Lon,gomlat5,gomlon5);contour(Lon,Lat,double(mask5),[0.5 0.5],'b')%% Location 6

gomlon8 = [138.75 138.75 133.75 133.75];gomlat8 = [-26.25 -21.25 -26.25 -21.25];[Lon,Lat] = meshgrid(lon,lat);mask8 = geomask(Lat,Lon,gomlat8,gomlon8);contour(Lon,Lat,double(mask8),[0.5 0.5],'b')%%
figuresst_gom = local(sst,mask7,'omitnan');t=1:736;figure(2)plot(t,sst_gom)axis tightdatetick('x','keeplimits')ylabel 'y'
As an example, I tried plotting the time series plot of location 7. I did this by making a mask of the location, then tried plotting the data within this mask. However I get a blank plot. Any advice?
Also as a note, I am using the Climate Data Toolbox by Chad A. Greene and tried following his example.
Thanks.
