Hello Carolina

You can add text annotations to your graph using the ‘textbox’ parameter of the “annotations” function. To add a list of strings to the textbox, you need to use a cell array. Add the following code snippet to your code to correctly pass the strings to the “annotations” function.

annotation('textbox', dim, 'String', {'Vcm1', 'Vcm2', 'Vcm3', 'Vcm4'}, 'FontSize', 15) 

If 'Vcm1', 'Vcm2', 'Vcm3' and 'Vcm4' are variables with numerical values, you can covert them to a string and pass them to the "annotation" function. Kindly follow the code scippet below:

txtAnnotations = sprintf('%.2f, %.2f, %.2f, %.2f',Vcm1,Vcm2,Vcm3,Vcm4);
annotation('textbox',dim,'String',txtAnnotations, 'FontSize',15)

You can refer to the following documentation link of the “annotation” function for further understanding:

I hope you find the above explanation and suggestions useful!
