Subject: st: Altering individual data markers in a graph
Hi,
I am trying to make a scatter plot (of eye pressure vs. age) and
change the color of particular markers. I have a variable called
"colorcode" in which I store a single letter depending on what color I
want the marker to be (i.e. B for blue, R for red, Y for yellow).
I tried doing this (see below), but it doesn't work:
gen col = "black"
replace col = "red" if colorcode == "R"
replace col = "yellow" if colorcode == "Y"
replace col = "blue" if colorcode == "B"
graph twoway (scatter pressure age, mcolor(col))
When I try to make the graph it says: "(note: named style col not
found in class color, default attributes used"
Any input on what I'm doing wrong and how I can fix it would be
greatly appreciated (or suggestions on other ways to do this).
Thank you!!!
