Coloured Scatter Diagram

Hi, 

 

I'm trying to create a scatter plot with two continuous variables. I'd then like to colour the plots according to a third, categorical variable.

 

Is this possible? 

 

My code so far is

 

proc sgplot data = sasuser.data1;
scatter x = tradingyears y = sales2015;
run;

Of course! 

Try adding the third variable as a GROUP var in your scatter statement. Example 1 in the documentation covers this

If you want to control the colours see the post below

Possibly more than you need now, but good to know:

Thanks, this is perfect, is it also possible to set the colour of the whole plot simply?

Re: Coloured Scatter Diagram

I'm not sure what you mean by 'whole plot'? 

 

Colours are usually defined by the Style set. If you're using SAS Studio this is likely HTMLBlue. For publications the style Journal/Journal1 are good. For a clean compact look, I like the Seaside and Meadow styles. Finally, there's a post on here that has the style definition in the style of Stephen Few.

Sorry I meant if I wanted to change the colour of the plots, when not splitting by the categorical variable. So just each dot.
