vbar 2 columns created by catt or coalesceC

[capam]

I have 2 columns (t1 and t2)  created by catt or coalesceC from multiple columns (v1:v4) similar to the below.

v1	v2	v3	v4		t1	t2
1					1
	2					2
		3			3
			4	-->	4
5						5
	7				7
			5		5
		8				8

I then run the following code. 

proc sgplot have;
	vbar t1;
	vbar t2;
run;

Then I get the following error message that I don't understand. 

ERROR: The same category variable must be used for summarized plots.

The error tells you pretty much everything.  VBAR takes as first parameter a category variable for summarisation.  You can only have one.  Why have the data in two columns?  Why not coalesce the t values an have a category variable:

v1	v2	v3	v4	T	cat
1				1	1
	2			2	2
		3		3	1

Then use cat as a group.

Can you give an example?

There is plenty of examples out there, first google hit:

Also, you may find this blog helpful, it covers everything graph orientated.

I finally found the solution I was looking for. Replace vbar in the above with vbarbasic as shown below:

proc sgplot data=have;
	vbarbasic t1;
	vbarbasic t2;
run;
