Hello,

I am trying to create a graph using the command xtline. The graph contains a line for the variable y for each one of the three groups in my panel (group is the panel var). However, I am interested in creating a graph that shows the same information as what I would obtain using xtline, but without connecting the data points, just showing the points the way they are, and showing a different symbol for each one of the groups. I tried to use the option connect(none), but it seems to do not be an available option for xtline (or I did not know how to add it to the command).

These are the instructions I am using to generate a graph that contains the three lines that plot the mean value of a variable "y" across time, for each of the groups.
Code:
    collapse y [weight=weighta], by(group year)
    xtset group year
    xtline y,  overlay legend(lab(1 "Group1") lab(2 "Group2") lab(3 "Group3") position(6) order(3 1 2))
If I include the option connect such as in the following lines, I obtain an error message.

Code:
 xtline y, plot(connect(none)) overlay legend(lab(1 "Group1") lab(2 "Group2") lab(3 "Group3") position(6) order(3 1 2))
connect(none) is not a twoway plot type
In addition, I want to add two shaded areas to my graph. One should cover the period 2015-2015.5 and the other one 2015.5-2016. Is this possible to do?

The following is a sample of my dataset:
