How to change the color in BARCHART

Coooooo_Lee — Tue, 04 May 2021 10:22:42 GMT

Hi there,

I just want to change the bar color in my GTL temple.

No group in my data, just want to show all bars in a same color, like the RED I specified here....
However, the bar color always black...

Anyone can help? Thanks!

proc template;
 define statgraph swimmer;
  begingraph / drawspace=datavalue;


  layout lattice / rows=1 columns=3 columnweights=(0.1 0.75 0.15) columngutter=0;

    layout overlay;
      entry textattrs=(color=white size=5) "blank";
    endlayout;

    layout overlay / walldisplay=none

        xaxisopts = (label="xxxxx"
                     labelattrs=(size=7)
                     tickvalueattrs=(size=7)
                     linearopts = (viewmin=0 viewmax=140
                                   tickvaluesequence = (start=0 end=140 increment=1)))


      yaxisopts = (label="xxxxxx"  
                     labelattrs=(size=7)
                     display=(label)
                     linearopts = (viewmin=1 viewmax=215
                                   tickvaluesequence = (start=1 end=215 increment=1)));


      barchart  x=obs y=dur /  orient=horizontal barwidth=0.1 fillattrs=(color=yellow);

        endlayout;

   
      layout overlay;
          entry textattrs=(color=white size=5) "blank";
        endlayout;   
    endlayout;
  endgraph;
  end;
run;

You should always include data for your program.

Lots of issues here, but try these:
1. You are explicitly setting start=, end=, and increment= options. That will result in either 140 or 215 bars, depending on the orientation. When you plot that many bars on a standard-sized plot, the fill will be small and you will mostly see the black outline of the bars

2. You set barwidth=0.1, which makes the bars even thinner. Again, this causes the yellow fill to be tiny.

3. You are setting orient=horizontal, which means that the YAXISOPTS apply to the X variable and the XAXISOPTS apply to the Y variable, which can be confusing.

Try modifying this code until you get what you need:

proc template;
 define statgraph swimmer;
  begingraph / drawspace=datavalue;
  layout lattice / rows=1 columns=3 columnweights=(0.1 0.75 0.15) columngutter=0;
    layout overlay;
      entry textattrs=(color=white size=5) "blank";
    endlayout;

    layout overlay / walldisplay=none
        xaxisopts = (label="xxxxx"
                     labelattrs=(size=7)
                     tickvalueattrs=(size=7)
                     linearopts = (viewmin=0 viewmax=140
                                   tickvaluesequence = (start=0 end=140 increment=20)))

      yaxisopts = (label="yyyyy"  
                     labelattrs=(size=7)
                     /*display=(label)*/
                     linearopts = (viewmin=0 viewmax=215
                                   tickvaluesequence = (start=0 end=215 increment=25)));

      barchart  x=obs y=dur / /*orient=horizontal*/ barwidth=1 fillattrs=(color=yellow);
        endlayout;
   
      layout overlay;
          entry textattrs=(color=white size=5) "blank";
        endlayout;   
    endlayout;
  endgraph;
  end;
run;

data A;
input obs dur;
datalines;
20   100
40   127
60   165
80   154
100  121
120   92
140   16
;

proc sgrender data=A template=swimmer;
run;

Hi Rick，

First thanks for sharing your idea. please see my replies below:

1. You are explicitly setting start=, end=, and increment= options. That will result in either 140 or 215 bars, depending on the orientation. When you plot that many bars on a standard-sized plot, the fill will be small and you will mostly see the black outline of the bars

The number here is based on my data, which is truly what I want.

2. You set barwidth=0.1, which makes the bars even thinner. Again, this causes the yellow fill to be tiny.

This is also what I want as there are too many bars need to be ploted here.

3. You are setting orient=horizontal, which means that the YAXISOPTS apply to the X variable and the XAXISOPTS apply to the Y variable, which can be confusing.

I do need to have a transposed barchart, this is also sepcified on purpose.

Is there a way to remove the black outline of the bars?

barchart x=obs y=dur / display=(fill) ...;

If you truly want all those bars, then you need to make the plot taller (for orientation=horizontal) or wider (for orientation=vertical). If you want a tall horizontal chart, use


ods graphics / width=640px height=1800px;  /* very tall */
proc sgrender data=A template=swimmer;
run;
ods graphics / width=640px height=480px; /* reset to standard dimensions */
