Different colors for bars

SoumeyaPierret — Tue, 18 Oct 2016 13:57:43 GMT

Hello everyone,

I don't know how to change the color only for one bar (for example just for desks) and keep the same color for all the other ones? Could you please help me ? Thank you very much

data error;
  input Product $  Revenue Upper Lower;
  datalines;
Desks  2000 2200  1800
Chairs 1500 1700  1300
Lamps  1200 1100  1300
;
run;

proc template;
  define statgraph errorbars;
    begingraph;
      entrytitle 'Product Revenue';
      layout overlay / yaxisopts=(offsetmin=0) xaxisopts=(display=(ticks tickvalues line));
     barchart x=product y=revenue;
        scatterplot x=product y=revenue / yerrorupper=upper yerrorlower=lower markerattrs=(size=0);
      endlayout;
    endgraph;
  end;
run;

Well, the two things jump to mind:

- Use a proc template step to define a styles for the graph, and set the colors for group 1 to be one color, then the other groups to the same color.

- Use two separate graph statements, one barchart statement for the first group setting the color, then another barchart statement for the rest of the data, setting the color there.

Add a group variable that has one value for the "desks" and another for everything else and use the GROUP option on the scatterplot statement to use that variable to display different color (and/or marker)

Another approach to consider is using a discrete attrmap and setting the group variable on the barchart to be the same as the category variable. In the attrmap, set the one category value to the desired color and the other values to another color. The benefit of this approach is that it will work regardless of data order.

Hope this helps!
