draws a horizontal line at the 0 value on the axis in boxplot

[echoli]

Hi All,

How can I draw a horizontal line at 0 value on the axis to make the 0 line more clear?

here is my code:

proc sgplot data=boxplot_BASILAR_VOL;
vbox BASILAR_VOL / category = group group = group
lineattrs=(pattern=solid) whiskerattrs=(pattern=solid);
xaxis display=(nolabel) type = discrete labelattrs = (size = 15pt Weight = Bold) valueattrs = (size = 20pt);
yaxis grid labelattrs = (size = 20pt Weight = Bold) valueattrs = (size = 15pt);
keylegend / location = inside position = topright across = 1;
run;

Thanks

Add an HREF line with the properties you want?

Another option is to change the lines to be light grey except for the 0 line.

Hi Reeza,

Coule you give me more explanation please? Can I make 0 line as black. My boxplot graph already have the light grey lines.

Thanks,

Sorry, it's REFLINE not HREF, you may want to play around with the THICKNESS option.

I can't test it because you're referencing your data. It's preferable to use code that references a dataset in SASHELP then we can test code as we suggest it. 

refline 0 / axis = y LINEATTRS=(Color=black thickness=10);
