Black and white fill patterns for bar graphs

DrAbhijeetSafai — Tue, 20 Feb 2024 13:14:00 GMT

I have googled a lot for more than 2 hours but I could not find a solution.

Problem: I want to use patterns in graphs, which I am able to do perfectly by using fillpattern keyword in vbar statement of proc sgplot. To this level all fine.

Now I want to continue using the patterns but do not want colors. I want to make it black and white. I am not able to understand how to do it.

Thanks in advance.

Please post the PROC SGPLOT statements that you are currently using.

Hi,

If you want to have empty bars with black lines for the patterns, you can add the NOFILL and FILLPATTERNATTRS=(COLOR=BLACK) options on your VBAR statement in PROC SGPLOT.

If you are creating grouped bars using the GROUP= option on the VBAR statement, you will also need to include the OUTLINEATTRS=(COLOR=BLACK) option to outline the bars in black.

Below is sample code to demonstrate this.

I hope this helps.

Marcia

proc sgplot data=sashelp.class;
  vbar name /  fillpattern nofill 
               fillpatternattrs=(color=black);
run;
/* Grouped bars */
ods graphics /attrpriority=none; 
proc sgplot data=sashelp.class;
  vbar name /  fillpattern nofill 
               fillpatternattrs=(color=black)
               group=sex outlineattrs=(color=black); 
run;

For groups, you might want to use the GROUPDISPLAY=CLUSTER option (unless you want a stacked bar chart):

ods graphics /attrpriority=none; 
proc sgplot data=sashelp.cars(where=(type^='Hybrid'));
  vbar type /  fillpattern nofill 
               fillpatternattrs=(color=black) groupdisplay=cluster
               group=origin outlineattrs=(color=black); 
run;
