How to label the data points of the graphic with their observation number

Maider — Thu, 29 Nov 2018 19:08:25 GMT

I have a dataset with different observations and I want to plot those points in a 2D plot with the next code:

PROC GPLOT DATA=components_corr;
PLOT Prin1*Prin2;
SYMBOL1 VALUE=plus COLOR=blue POINTLABEL= ??;
RUN;

But I dont know what to write in pointlabel in order to obtain a plot with different points and the number of observation of each point on it.

I think your best choice is to use the Statter Statement in PROC SGPLOT (Not GPLOT).

Do a Google seach or check out the Graphically Speaking blog for examples.

Here is a minimal example using the SASHELP.CLASS data set with Proc SGPLOT

proc sgplot data = sashelp.class;
   scatter x=height y=weight/datalabel=name;
run;

you can use any of the variables in the data set with DATALABEL option to provide a label for the points. I recommend not using ones with long text though.

If you have the observation number in the data use your variable name. If you don't , add it to the data prior to plotting possibly with something like

data toplot;
   set components.corr;
   obs=_n_;
run;

and use the toplot data set and datalabel=obs.
