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.
