Hello I want to show principal component axis next to original axis (before rotation) in iris dataset for first 2 dimension but I don't know how. I attached an example photo. also my question is "What determines the magnitude of the principal component axis?" ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1238027/image.png)
