proc sgplot / custom scale for xaxis

Cruise — Wed, 21 Feb 2018 00:57:54 GMT

I'd like to create a Plot 1 without the empty space with no information. Ideally, I want to show xaxis only for the range of 0.004-0.006 keeping CI95% brackets as narrow as shown in plot1. However, every time I use min, max, offsetmin, offsetmax options or values=from to by, or xaxis min=0.004 options in the code, 95%CI brackets become so wide as shown in Plot 2 which is not desirable. Please help how to create Plot 1 but without the empty space in front.

Plot 1. Desirable dimension and style of plot for narrow CI95%. But I would like to eliminate the space without information until from 0 to 0.004

Plot 2. Undesirable style but resulted from code with xaxis min=0.004

proc sgplot data=data;
   scatter y=Risk x=Rate/ xerrorlower=LowerCL xerrorupper=UpperCL
           markerattrs=(symbol=diamondfilled)
           group=Type groupdisplay=cluster;
   xaxis grid min=0;
   yaxis grid colorbands=odd discreteorder=data type=discrete;
   label Rate = "Rate";
run;

Don't set the min=0 on the xaxis statement. Then you will not get the empty space.

The CI bar widths depend on the values in the data you are providing and scaled with the x-axis.

@Jay54

Thanks Sanjay. Commenting out min=0 resulted in widened 95CI. Desirable plot is narrow and tall CI95 as shown in plot 1.

proc sgplot data=p.alb_conc;
   scatter y=Risk x=Rate/ xerrorlower=LowerCL xerrorupper=UpperCL
           markerattrs=(symbol=diamondfilled)
           group=Type groupdisplay=cluster;
/*   xaxis grid min=0.004;*/
   yaxis grid colorbands=odd discreteorder=data type=discrete;
   label Rate = "Rate";
   title 'hi';
run;

The CI bar widths are scaled to the x-axis based on the values you provide in the LowerCL and UpperCL variables in the data set. It is the same in both the graphs. Plot 1 has bigger range on the x-axis, so the same bar widths look smaller. The only way to change them is if you change the values in the LowerCL and UpperCL variables in the data set.

Sanjay, I'm using noautolegend, do you know how to label for each type=discrete in legend on the side of the plot? any reference document for the similar plot?

If you leave out the NOAUTOLEGEND you will get the default legend at the bottom. You can customize its position by using a KEYLEGEND / position=right across=1;
