How to set background colors in sgplot conditioned on both x- and y-values

[AnnaHawgood]

Hi

I've made the following scatterplot with sgplot and would like to add background colors, so that:

• the top right corner (defined by x>0.75, y>0) is green
• the bottom left corner (define by x<=0.75, y<=0) is red
• the top left and bottom right corners (x<=0.75, y>0 and x>0-75, y<0) are yellow

Is there a way of doing this in proc sgplot (I have attached my data as a xlsx-file)?

Graph:

  

Code:

title "Lovoverholdelsesprocenter over tid - §50-Undersøgelser";
 proc sgplot data=graf dattrmap=attrmap_bu noborder ;
  where sagstrin ? "2" and 'Med i Baselin'n ne '';
  scatter x=pct_118 y=diff / group=spg attrid=spg;
  styleattrs datacolors=(red yellow green);
  xaxis min=-0 max=1 values=(0 to 1 by 0.1) fitpolicy=rotate valuesrotate=diagonal valueattrs=(Family=Helvetica Size=8) label="Lovoverholdelse 1. kvt./18";
  yaxis min=-0.4 max=0.5 values=(-0.4 to 0.5 by 0.1) valueattrs=(Family=Helvetica Size=8) label="Frem-/tilbagegang ift. 4/17 i procentpoint";
  refline 0 /axis=y;
  refline 0.75 /axis=x;
  *keylegend "underniv" / across=3 noborder valueattrs=(Family=Helvetica Size=7);
run;

If you know the data extents, use POLYGON plot to display the 4 regions you want.
