## Scatter plot with multiple x independent variables

I'm working with the SAS University Edition, and I'm having trouble creating a scatter plot from a dataset with three X variables. It seems like this should be really simple, but I can only seem to add one X value. I have a homework assignment where my instructor asked us to "Plot the observed data and the two fitted regressions on one plot (this is probably easiest done by hand over a scatterplot of the data)." Here is the data set:

 Obs CITY Y X1 X2 X3 1 1 11.2 587 16.5 6.2 2 2 13.4 643 20.5 6.4 3 3 40.7 635 26.3 9.3 4 4 5.3 692 16.5 5.3 5 5 24.8 1248 19.2 7.3 6 6 12.7 643 16.5 5.9 7 7 20.9 1964 20.2 6.4 8 8 35.7 1531 21.3 7.6 9 9 8.7 713 17.2 4.9 10 10 9.6 749 14.3 6.4 11 11 14.5 7895 18.1 6 12 12 26.9 762 23.1 7.4 13 13 15.7 2793 19.1 5.8 14 14 36.2 741 24.7 8.6 15 15 18.1 625 18.6 6.5 16 16 28.9 854 24.9 8.3 17 17 14.9 716 17.9 6.7 18 18 25.8 921 22.4 8.6 19 19 21.7 595 20.2 8.4 20 20 25.7 3353 16.9 6.7

## Re: Scatter plot with multiple x independent variables

Can you provide an example of what such a plot would look like?

## Re: Scatter plot with multiple x independent variables

I don't think so, because I'm not even sure what it would look like myself... unless my instructor means I should create a separate scatterplot for each X variable?

## Re: Scatter plot with multiple x independent variables

I think he's asking us to do something like what's being done in this video using a different program... https://www.youtube.com/watch?v=_5kRBBqQhA0

## Re: Scatter plot with multiple x independent variables

PROC SGSCATTER will create such a scatterplot with 3 x-variables and one-y variable. An example is given here:
