Regression line / trendline in GPLOT Bubble Chart

brookeewhite1 — Thu, 30 May 2019 18:19:20 GMT

Is it possible to add a trendline / regression line to a bubble chart created with gplot? I have a gplot statement similar to this, which successfully creates a bubble plot, however I want to add a trendline. I saw options for doing this on scatterplots but couldn't find anything for a bubble plot. I am programming within SAS Enterprise Guide 7.1. Thanks in advance!

proc gplot data=LIBNAME.MYDATA;

bubble Errors*Volume=share / bsize=7 bcolor=clear

bfill=solid

ctext=black cframe=white

haxis=axis1 vaxis=axis2

href=16 chref=blue lhref=2

vref=5 cvref=blue lvref=2

annotate=labels;

run;

quit;

It's certainly possible in PROC SGPLOT.

I suspect it is possible (but haven't actually tried) in PROC GPLOT by using the I=RL option in the SYMBOL statement.

You can overlay the Bubble and Reg Plots with PROC SGPLOT like this

title 'Bubble Plot with Regression Line';
proc sgplot data=sashelp.class noautolegend;
  bubble x=height y=weight size=age;
  reg x=height y=weight / nomarkers;
run;
title;

Thank you, draycut!

This did produce a nice looking chart with regression line. I had quite a few options specified in GPLOT. Now that I've switched from GPLOT to SGPLOT, I'll see if I can find the same or similar options available under SGPLOT.
