Hello Alex,

- What #labels: is for exactly?
It changes the label string in y axis. By default it is #yourself. For example, you can do:

| diagram |
diagram := ESDiagramRenderer new.
(diagram verticalBarDiagram)
y: [:each | each];
labels: [ :each | each value asString, '%' ];
identifier: #yourself;
defaultColor: Color blue;
valueAxis;
width: 500;
rotatedLabels: false;
models: (1 to: 21).

- How can I get the label on the vertical axis as float (with 2 decimal), but not fractions.
You can use #labels: for that. For example:

| diagram |
diagram := ESDiagramRenderer new.
(diagram lineDiagram)
y: [:each | each];
labels: [ :each | each value asTruncatedFloat ];
defaultColor: Color blue;
valueAxis;
width: 500;
rotatedLabels: true;
models: (1 to: 13) / 16.

Hi!

Based on some example (e.g., below), I inferred that #valueAxis set on labels for the vertical axis. The one on the horizontal axis are set by #identifier:

I have produced the following curve. How can I get the label on the vertical axis as float (with 2 decimal), but not fractions. 

I will use your answers to comment some of the method in EyeSee. 

Cheers,
Alexandre
