Hello, I am working on the model's run performance evaluation, in this regard I want to plot a taylor diagram. I am using cgtaylordiagram, but this code generate only positive correlations on plot as my data have some negative correlations as well with respect to the observed dataset. Further more I need some guidance regarding the RMS corporation in taylor diagram. Kindly provide me a code or a specified method so that I can plot negative correlation as well in the diagram.
