Lasso Plot Datatip Shows only X and Y

hi community I am trying to figure out how I can modify the lasso plot so that the datatip shows the name of the selected coefficient with a fitted value, the L1 norm of a set of coefficients including the selected coefficient, and the index of the corresponding Lambda. I am basically following the example included in the documentation Trace plot of lasso fit - MATLAB lassoPlot (mathworks.com), however my lassoplot only shows x and y instead of the helpful information I need. I am using Matlab Online version, and I have tried didfferent data to

Here is a screen of how mine datatip only shows X and Y value:

Hi Skrowh,

I followed the documentation and have simulated the example you mentioned. However, I was unable to reproduce the error you referred to. In order to assist you better, kindly share the complete code that is producing this error.

Below is the code that I have simulated. Please run this code and let me know if you get any error with this code.

load acetylene 

X = [x1 x2 x3]; 
D = x2fx(X,'interaction'); 
D(:,1) = []; % No constant term 

B = lasso(D,y); 

lassoPlot(B,'PredictorNames',{'x1','x2','x3','x1.*x2','x1.*x3','x2.*x3'}); 
legend('show','Location','NorthWest') % Show legend 

Hope this helps!
