So, attending to the request Doru made, here's something similar to the example he provided in EyeSee... All the methods were already implemented but most of them didn't have a clear accesor to modify them.

So, if you just load the last version of GraphET and do this:

builder := GETDiagramBuilder new.

grouped := { #item1->{10 . 12 . 11 . 14 } . #item2-> { 1 . 1 . 20

}

. #item3->{ 1 . 1 . 1 . 1 . 1} }.

diag := (GETVerticalBarDiagram new)

modelLabels: [:each | each key ];

y: [:each | each value size];

yAxisLabel: 'Count';

valueAxis;

height:200;

spacing:20;

yAxisOnRight;

color: Color veryLightGray;

axisColor: Color veryLightGray;

models: grouped;

yourself.

diag2 := (GETVerticalBarDiagram new)

y: [:each | each value sum];

regularAxis;

height: 200;

spacing:20;

yAxisLabel: 'Sum';

color: (Color red);

axisColor: (Color red);

models: grouped;

yourself.

(builder unionDiagram)

add: diag;

add: diag2.

builder open

You'll see it's very similar. There's two things I couldn't replicate so far, one of them is the rotating labels, as Roassal can't rotate labels yet, and the second one was the GapFraction, as axis in GraphET need some work yet, so implementing that kind of thing would be hard. I think I'll dedicate to a proper axis in the next couple of weeks.

Cheers :)!
