PROC SGPLOT how to get more diverse colors

Cruise — Fri, 15 Apr 2022 06:25:59 GMT

Hi Folks,

I'm using proc sgplot in SAS 9.4-1M5.

Datacolors=green is too dark and Datacolors=lightgreen produces too bright green bars to the plot's background I have to stick to.

Do you know color codes or ways that I can specify in the sgplot for more diverse green options? I need green some where between these dark and bright green options.

proc sort data=swimmer; by BOR; run;
PROC SGPLOT DATA=SWIMMER; 
STYLEATTRS DATACOLORS=(LIGHTGREEN YELLOW ROSE);

Thank you for your time in advance.

If you go to this link you will find that SAS supports multiple ways to define colors: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.4/graphref/p0edl20cvxxmm9n1i9ht3n21eict.htm

If you don't want to learn one of the numeric coding systems like RGB, CMYK I suggest that you look at the page for "Color Naming System" or CNS. That uses more modifiers for color where you combine the elements of Lightness, Saturation and Hue from the following table.

So you could have

Verydarkgreen

Verydarkgrayishgreen

Verydarkmoderategreen

Verydarkstronggreen

Verydarkvividgreen

(replace VeryDark with Dark, Medium,Light or verylight)

This system also allows combine colors that are adjacent (green is adjacent to blue) so you can use

BlueGreen, GreenBlue, YellowGreen, GreenYellow. Or to have one of the colors contribute a bit less add "ish"

YellowishGreen, GreenishYellow.

Along with the other lightness and saturation options.

So you can have MediumModerateYellowishGreen for example.

BLACK and WHITE will be that regardless of other elements.

Lightness	Saturation	Hue
Black	Gray	Blue
Very Dark	Grayish	Purple
Dark	Moderate	Red
Medium	Strong	Orange/Brown
Light	Vivid	Yellow
Very Light		Green
White

You can use function Palette() in IML.

proc iml;
greens9 = Palette("GREENS", 9);
print greens9;
quit;

For a discussion of SAS color-naming schemes (with examples) see "Three ways to specify colors in SAS statistical graphics procedures,"

Here's an example of how to specify different shades of greens on the STYLEATTRS statement:

proc sgplot data=sashelp.cars;
styleattrs datacolors=('Light Brownish Green' 'DarkOliveGreen' 'SeaGreen');
vbar Cylinders / group=origin;
run;
