GPLOT Legend Style

[MorningPanda]

Hi all,

I am creating a line plot with gplot procedure, and would like to change the appearance of the legend.

Below are my codes.

The look of my legend is 

But the style I want is 

I know that I can use repeat = N to control the number of dots in the legend,

and I can use shape = symbol(width, height) to change the size and width of the the legend.

But if I am using both, say 

legend1 label = NONE repeat = 1 shape = symbol(50 pt, 10 pt) FRAME position = (TOP RIGHT INSIDE);

It will end up to be like this

i.e. by defining repeat = 1, I am losing the ability of changing the width of legend shape.

Does anyone know how to do it? 

Thank you!

Move to proc sgplot and GTL, gplot is really old.  When you do you will have a lot more control over your graphs and will find it far simpler.  You can read through the posts in this blog:

Which have examples of anything you can think of with code.

Unfortunately, I don't think gplot's legend statement will let you do what you're wanting.

But, as always, if you're willing to do a little extra custom coding, you could 'fake' the legend you're wanting with annotate:

data anno_legend;
length function $8 style $35 text $100;
xsys='1'; ysys='1'; hsys='3'; when='a';

function='move'; x=50; y=95; output;
function='draw'; x=60; line=1; color='black'; size=.001; output;
function='label'; x=55; position='+'; style='albany amt/unicode'; text='25cf'x; color='black'; size=4.0; output;
function='label'; x=61; position='>'; style=''; size=2.5; text='Super drug'; output;

function='move'; x=75; y=95; output;
function='draw'; x=85; line=3; color='black'; size=.001; output;
function='label'; x=80; position='+'; style='albany amt/unicode'; text='25cb'x; color='black'; size=4.0; output;
function='label'; x=86; position='>'; style=''; size=2.5; text='Old drug'; output;
run;
