How do I correct this simple mista

[desireatem]

When I plot thes plots, the name on the plot suppose to be " Plot _SENSIT_A      _SENSIT_B" however I am getting " Plot sensitivity      _SENSIT_B.

How do I correct it?

You used the LABEL statment to add a label for the _SENSIT_A variable, so that label is being used for the legend.  You should post questions like this to the SAS/GRAPH Support Community: https://communities.sas.com/community/support-communities/sas_graph_and_ods_graphics

If you are interested in learning the modern ODS statistical graphics, here is how to create the plot with PROC SGPLOT:

title "Comparison of Models A and B";

PROC SGPLOT data=new;

label _SENSIT_A="A" _SENSIT_B="B";

series x=_1MSPEC_ y=_SENSIT_A / markers;

series x=_1MSPEC_ y=_SENSIT_B / markers;

xaxis label = '1 - Specificity';

yaxis label = 'Sensitivity' grid;

run;
