Hello,

I made a prediction price model and I would like to, in my graph in visualizations part of an exampleset generate , create a line when the price prediction is equal to the real price or, in a nutshell when x = y.

How can we do that ?

Thanks a lot for your answer

Hi @alois_borgognon ,

Do you mean the linear interpolation between the label and prediction?

Oh, sorry I missed the point that you want to have a diagonal line y=x

You can add a new Plot 2 for the label
