Changing default line patterns / colors of ROC curve output

marurif — Wed, 25 Mar 2020 00:01:07 GMT

Is there a way to change the line patters and colors of the output of ROC curves derived from pro logistic?

I get this picture, but I would like to change to gray scale and more distinct line patterns.

I used a template, and I've been able to change the line thickness and the fonts, but I can't seem to change the color of the lines or the line patterns.

Any ideas?

Thanks

proc logistic......
model ......../outroc=roc ;
run;
could get the data to plot ROC curve,
and using PROC SGPLOT to plot it by yourselef .
@Rick_SAS has written a blog about it before.

What version of SAS are you running?

%put &=SYSVLONG4;

Thanks, but that is not the information we need. Please submit the statement

%put &=SYSVLONG4;

and send the value that is displayed in the log. It will look something like this:

7529 %put &=SYSVLONG4;
SYSVLONG4=9.04.01M6P11072018

It would be great to see the code you are using to generate the ROC curve. In general, you have three options:

1. Use an ODS style. For grayscale and line patterns, use the JOURNAL style:

ods HTML style=Journal;
proc logistic data=Sashelp.Class;
model Sex = height weight age;
roc height;
roc weight;
roc age;
run;

2. Use one of the techniques in the SAS/STAT documentation chapter "Statistical Graphics Using ODS."

The %MODSTYLE macro is often effective.

3. As KSharp suggested, write the data to a SAS data set and use PROC SGPLOT and use the features in that procedure to control the attributes of the curve. If the data is in "long form," use the STYLEATTRS statement. If you use multiple SERIES statement, use the LINEATTRS= option.

Thanks.Using proc sgplot and customizing the output is working.

Using PROC SGPLOT to customize the ROC curves worked. Thanks.
