Hi folks,

I am Pablo Estefó an ObjectProfile engineer and I will continue the excellent work of Daniel Aviv on Graph-ET (on Roassal2).



I’ve just added the “oblique” labels feature(for Roassal2’s GraphET version only). And the result is something like this:

=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~
| diagram   |
diagram := GETDiagramBuilder new.
diagram horizontalBarDiagram
models: #(0.2 0.5 2 0.3 0.51 1);
color: [ :x | x <= 0.5 ifTrue: [ Color blue alpha: 0.2 ] ifFalse: [Color blue alpha: 0.5]];
valueAxisLine;
baseAxisLine;
addValueDecorator: (GETRegularTickDecorator new numberOfTicks: 5);
addValueDecorator: (GETRotatedLabelDecorator new diagonal numberOfLabels: 5).

diagram open
=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~

It produces:

If we change the rotated label as diagonal inverted:

=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~

valueAxisLine;
baseAxisLine;
addValueDecorator: (GETRegularTickDecorator new numberOfTicks: 5);
addValueDecorator: (GETRotatedLabelDecorator new diagonalInverted numberOfLabels: 5).

addValueDecorator: (GETVerticalLabelDecorator new numberOfLabels: 5).

I am thinking a succinct way to specify it.

Well, as you can see the axis configuration will get more complex the more options we can provide. 
So our next question to drive our development is:
How can we get the richest input in order to interpret it and return the best plot with the minimum configuration input.

I would like to know your opinions to develop a better Graph-ET :-)


Cheers,
Pablo
