How to plot Taylor diagram for four time series.

Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

('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:

https://www.mathworks.com/matlabcentral/fileexchange/20559-taylor-diagram

And the attached allstats.m was from https://github.com/gmaze/gmaze_legacy/blob/master/matlab/codes/statistics/allstats.m

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

Thank you very much. The codes worked perfectly.
