Adding markers or Data Points off carpet

Currently, I have a carpet plot formed from abut 13 data points using Plotly. I would like to visualize the accuracy of the current carpet and compare the carpets prediction vs actual data. To do this I would like to plot the carpet as well as new data points that are not on the carpet for any new data we output. Is there a way for us to plot data points accuracy in relation to the carpet (i.e. plot the carpet as well as a scatter plot with some data points off the carpet)?
