Improved Grapher way of stacking data

Hi!

Just to share an improvement of Grapher, which is part of Roassal.

The code:

| b d classes |

classes := (Collection withAllSubclasses reverseSortedAs: #numberOfMethods) first: 10.

b := RTGrapher new.

d := RTVerticalMultipleData new.

d points: classes.

d addMetric: #numberOfLinesOfCode.

d addMetric: #numberOfMethods.

d barChartWithBarTitle: #name rotation: -30.

b add: d.

Produces:

And this code:

| b d classes |

classes := (Collection withAllSubclasses reverseSortedAs: #numberOfMethods) first: 10.

b := RTGrapher new.

d := RTHorizontalMultipleData new.

d points: classes.

d addMetric: #numberOfLinesOfCode.

d addMetric: #numberOfMethods.

d barChartWithBarTitle: #name rotation: -30.

b add: d.

Produces:

Naturally, you can add several metrics:

Consider:

| b d classes |

b := RTGrapher new.

d := RTHorizontalMultipleData new.

d points: #( #('hello' 1 2 1) #('world' 2 4 2) #('bonjour' 3 5 4) #('Gutten Morgen' -1 4 -5)).

d addMetric: #second.

d addMetric: #third.

d addMetric: #fourth.

d barChartWithBarTitle: #first rotation: -30.

b add: d.

And:

| b d classes |

b := RTGrapher new.

d := RTVerticalMultipleData new.

d points: #( #('hello' 1 2 1) #('world' 2 4 2) #('bonjour' 3 5 4) ).

d addMetric: #second.

d addMetric: #third.

d addMetric: #fourth.

d barChartWithBarTitle: #first rotation: -30.

b add: d.
