How to create a graph with area filled in under the line

zhuxiaoyan1 — Thu, 16 Feb 2017 20:42:26 GMT

I want a line with Pap on the x-axis and Avg on the y-axis. the value on x-axis and y-axis should be the same order as in the data. the value on the y-axis should be from 50000 to 35000 with 5000 apart. The area under the line needs to be filled. Any suggestions or ideas will be greatly appreciated!

Avg Pap

See the 2D area plot on this page:

http://robslink.com/SAS/democd7/aaaindex.htm

I like to start here when creating graphs, since it has both the code and image. One drawback is that it uses GPLOT procedures when SG Procs are more common these days, SGPLOT.

With SGPLOT, you can try using the BAND plot, with constant value for the bottom edge.

From @Jay54 SGPLOT with BAND works like a charm, set the lower bound to 0 if you want the area filled in.

Thanks for posting sample data, preferably in a data step in the future, which is the first step in my code below.

data have;
    informat value comma. cat $5.;
    format value dollar20.2;
    input value cat;
    start=0;
    cards;

Cool.

If the x-axis is really discrete, maybe a VBARPARM would work better? Not sure what "slope" means between to category values.

proc sgplot data=have;
vbarparm category=cat response=value / barwidth=1 fill nooutline;
yaxis values=(0 to 35000 by 5000);
xaxis valuesrotate=vertical valueattrs=(size=6) discreteorder=data;
label value='Avg Amount' cat='PAP';
run;

It was sorted continuously so I'm assuming some ranking? I would suspect, your correct and either VBARPARM or HBARPARM would be a better graphing modality. I would suggest HBARPARM as it makes the categories more legible.

Thanks very much for the help! I got the graph. But my xaxis is croweded with all the values of Pap. I want to get rid off it and just keep the label "PAP". How should I do that? Thank you again.

On the XAXIS statement, add: ddisplay=(noticks novalues)

It works. Thank you very much!

good suggestion. Another question. How to change the font and size of the labels? Thanks!
