('Sample data.xlsx')
I have the above five different datasets, i want matlab code to execute Taylor diagram for the dataset taking correlation between insitu and each of the other four model data in the sample data. Kindly help. Thanks.

There doesn't appear to be any function for making a taylor diagram in MATLAB. I suggest trying on of these FEX submissions.

Here's how:
Download this:
Then use this code:
myData = readtable('Sample data.xlsx');
% STATM(1,:) => Mean
% STATM(2,:) => Standard Deviation (scaled by N)
% STATM(3,:) => Centered Root Mean Square Difference (scaled by N)
% STATM(4,:) => Correlation
stat1 = allstats(myData.insitu,myData.era5);
stat2 = allstats(myData.insitu,myData.ncar_ncep);
stat3 = allstats(myData.insitu,myData.merra2);
stat4 = allstats(myData.insitu,myData.ceres);
STDs = horzcat(stat1(2,:),stat2(2,2),stat3(2,2),stat4(2,2));
RMSs = horzcat(stat1(3,:),stat2(3,2),stat3(3,2),stat4(3,2));
CORs = horzcat(stat1(4,:),stat2(4,2),stat3(4,2),stat4(4,2));
[pp tt axl] = taylordiag(STDs,RMSs,CORs);
for ii = 1 : length(tt)
set(tt(ii),'fontsize',9,'fontweight','bold')
set(pp(ii),'markersize',12)
set(tt(ii),'String',strrep(myData.Properties.VariableNames{ii+1},'_',' '));
end

Dear Meg Noah,
Thank you so much for your reponse, it's very useful, finally, I am able to draw taylor diagramn following your steps.
Best regards
