Hi lily,
To answer your questions more or less in order:
rainbow() is an easy way to get a small number of distinct colors. You
only had nine unique values in "dfm$A". Obviously it gets harder to
distinguish colors when you have more of them, so just increasing the
number that rainbow() returns wi
For more than 10 records, how to reformat the colors? Also, how to show the
first legend only, but at the bottom, while the second legend in your code
is not necessary? In all, the same A values have the same color, but
different symbols in DF==1 and DF==2.
Thanks for your help.

Hi Jim,
For true color, I meant that the points in the figure do not correspond to
the values from the dataframe. Also, why to use rainbow(9) here? And the
legend is straight in the middle, is it possible to reformat it to the very
bottom? Thanks again.

Hi lily,
As I have no idea of what the "true record" is, I can only guess.
Maybe this will help:
# get some fairly distinct colors
rainbow_colors<-rainbow(9)
# this should sort the numbers in dfm$A
dfm$Acolor<-factor(dfm$A)
plot(dfm$B,dfm$C,pch=ifelse(dfm$DF==1,1,19),
col=rainbow_colors[as.numeri
Hi R users,
I still have the problem about plotting. I wanted to put the datasets on
one figure, x-axis represents values B, y-axis represents values C, while
different colors label column A. Each record uses a circle on the figure,
while hollow circles represent DF=1 and solid circles represent D
