Drawing arrow as annotation on the proc splot

[DanH_sas]

On the SERIES plot, set LINEATTRS=(thickness=1) and see what you get.

Thanks @DanH_sas ! It works, the line is thin now, but then how to control the dot / solid line and also the color? I just want all the same color, I have specified it but seems not working? styleattrs datacolors=('CXC00000') datalinepatterns=(dot solid);

[Esterina]

Oh sorry... actually I see when I specified lineattrs=(thickness=1), the arrowhead size is just the same as previously with vector... so seems I have no concrete solution to make it smaller than the default size = 1

[DanH_sas]

After further investigation, the effective minimum size for the arrowhead on the series plot cannot be smaller than 8 pixels.

[DanH_sas]

You can force the same color by setting the color on the LINEATTRS option:

LINEPATTRS=(color=cx000000 thickness=1)

[DanH_sas]

Oh, remove the THICKRESP option as well, because that will make the line thickness vary based on the value of "m".

[DanH_sas]

THICKRESP changes the thickness of the line based on a response variable. If you care only about the size of the arrowhead, then you probably will not require that option.

OK. You also could use TEXT to control ARROWHEADER size .

NOTE: you have to use UNICODE SAS to run code.

data x;
input x y x0 y0    group   x1 y1 r;
triangle=unicode('\u25B2');
cards;
0 0  1  0   1  1 0 -90
0.5 -1 0.5 1   2  0.5 1 0
0.5 0.5  1 1   3  1 1 45

proc sgplot data=x;

text x=x1 y=y1 text=triangle/group=group strip contributeoffsets=none rotate=r textattrs=(size=4);  /*<--Change this*/
