Can you add data points to Least Squares Means Plots?

Within Fit Model, are you able to add your data points to the LS Means Plot?

If data points are rows, then yes.
Just save the script to the data table and re-run it after you add data.

...or RTM>Redo>automatic recalc, and as you add rows the models updates

To add to @Byron_JMP response. If you use a data filter, and set up a column that discriminates between your original data, and the new data points that you have added, you can specify to only use the original data to generate the model, but show the new data points along with the original points on the LS Means plot.

Thank you both for your replies. I think I either did not explain my problem well or I'm not understanding your responses. My experiments are complete and my model is up to date. Attached is the LS Means Plot I'm working on. @Byron_JMP, if I save my script to my data table and re-run it I get the same result but I'm not changing anything so I'm guessing that makes sense. @txnelson, within the local data filter I see the show and include buttons but even if I select certain factors from my experiment to show or include it doesn't change my plot in any way. I want to see all of my data points on the LS Means Plot and I'm using JMP 18.0.1 if that helps.

I don't know the LS Mean platform. But what you could do in the "Standard Least Squares" is, to go to the red triangle and "Save Columns ->Prediction and Interval Formulas". Then you go to the Graph Builder from your data table. Drag your input variable to the x-axis, the prediction formula as well as the actual data column to the y-axis and the upper and lower mean formulas to "Interval".

In my example I had a factor with five levels, the red points and intervals are the mean prediction with confidence interval and the blue points are actual data points.
