SGploy symbol

[John70]

Dear All,

Need help.  How to choose symbols, such as circle for trt 1, triangle for trt 2, and diamone for trt 3, in the following sgplot program (SAS 9.2) or attachment.   Thanks!!

data test;
input trt temp value sd sdlo sdhi;

What version of SAS are you running?

[John70]

I use SAS 9.2

[Jay54]

With SAS 9.2, you will have to build a custom style to get the marker shapes you want.  To ensure you will get the correct marker regardless of their position in the data, I normally just add dummy values in the data with group values I want at the top..  The X or Y values can be made missing to prevent plotting of these dummy values.  but these values ensure the assignment of all the group (or treatment) values and their order.

With SAS 9.2 GTL, you can use the INDEX option, and place the index values of the style element 1-12 in the data.

With SAS 9.3, you can use DiscreteAttrMap to deterministically tie specific marker shapes to specific treatment values.

If you have multiple columns instead of groups, you add a scatter plot for each treaatment and just set the mMARKERATTRS for each plot statement.

Hi Sanjay,

thanks!  it works.

[Jay54]

Which method did you go with?

[John70]

make  multiple columns instead of groups, plot for each treaatment and just set the mMARKERATTRS for each plot statement.   Thanks!

You should also look at the MODSTYLE style modification macro. It might provide you with enough flexibility for your purpose.. It is documented here : http://support.sas.com/documentation/cdl/en/statug/63347/HTML/default/viewer.htm#statug_odsgraph_sec...

Hi PG,

Sounds it is a great way to work on this but I am new in SAS program. it will take me sometime to understand this.

Thanks!

John

Hi PG,

Your suggestion works!  but how can I let legend show the corresponding symbols, not the line since the line is the same?  see attachment.

Thanks!

John

Note NAME option on scatter plot addition of KEYLEGEND stmt.

proc sgplot data=test;

xaxis  label='Temperature' ;
yaxis  label="solicity" ;
title "";

series x = temp y = value / group=trt markerattrs=(size=9  color=black) ;
scatter x = temp y = value / group=trt markerattrs=(size=9 color=black) name='s';
keylegend 's';

run;

[John70]

Thanks Sanjay!!!

one more question, why when output the figure as rtf,  the lines and marks in the figure are not right (see attachment) again?

John

[Jay54]

On RTF, the default style has colored lines and markers.  You already set all markers to black.   If you want the lines to be black too, set the lineattrs on the series plot statement.  For thicker lines use - lineattrs=(color=black thickness=2).

Alternatively, you can just use STYEL=JOURNAL on the ODS RTF statement to get a fully black and white graph.  Then you don't need to set the line and marker attrs to black.

proc sgplot data=test;

xaxis  label='Temperature' ;
yaxis  label="solicity" ;
title "";

series x = temp y = value / group=trt lineattrs=(color=black) ;
scatter x = temp y = value / group=trt markerattrs=(size=9 color=black) name='s';
keylegend 's';

run;

Hi Sanjay,

Many thanks!!  I tried per your suggestion, however the symbols in the RTF output were not what I wanted.  Instead of circle, triangle, and square specified by the program, the RTF output gave circle, +, and x.  When the plot was made without ODS rtf output, the SGPLOT gave a right symbols.  It seems that somehow %modstyle was affect by ODS. Could you please help on this?   Thanks!  John

(also refer the attached program)

The following program provides correct symbols.

%modstyle(name=markstyle, parent=statistical, type=CbyLbyM,
          markers=circle triangle square)
ods listing style=markstyle;

proc sgplot data=test;

xaxis  label='Temperature' ;
yaxis  label="Solicity" ;
title "";

series x = temp y = value / group=trt lineattrs=(pattern=solid color=black thickness=1) ;
scatter x = temp y = value / group=trt yerrorlower=sdlo yerrorupper=sdhi markerattrs=(size=9 color=black) name='Toto';
keylegend 'Toto'/position=topright location=inside across=1;

run;

The following program, when add rtf output, fail to provide correct symbols.

ods graphics on/noborder ; 
ods rtf file='C:\SAS\test1.rtf';

%modstyle(name=markstyle, parent=statistical, type=CbyLbyM,
          markers=circle triangle square)
ods listing style=markstyle;

proc sgplot data=test;

xaxis  label='Temperature' ;
yaxis  label="Solicity" ;
title "";

series x = temp y = value / group=trt lineattrs=(pattern=solid color=black thickness=1) ;
scatter x = temp y = value / group=trt yerrorlower=sdlo yerrorupper=sdhi markerattrs=(size=9 color=black) name='Toto';
keylegend 'Toto'/position=topright location=inside across=1;

run;

ods rtf close;
