Draw math functions with EyeSee
 
|
Hi all,
i try to use EyeSee to plot mathematical functions with ESLineDiagram. They is not easy as i might expect at the beginning :-) The problem is EyeSee is using collections as models. I try to transform the function as a collection like above but maybe there is a better way to do that. |diag f functionAsModel| f := [:x | x*x]. functionAsModel := (0 to:10 by:0.1) collect:[:each | f value:each]. diag := ESDiagramRenderer new. (diag lineDiagram) y: #yourself; yAxisLabel: 'X^2'; rotatedLabels: true; regularAxis; defaultColor: Color green; models: functionAsModel. diag open Regards, -- Serge Stinckwich UMI UMMISCO 209 (IRD/UPMC), Hanoi, Vietnam Every DSL ends up being Smalltalk http://doesnotunderstand.org/ _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

I would love to have a Pharo-based solution for doing numerical analysis. This implies having a .pdf (or .ps, if simpler) exporter of the graph.

You can set the function as #y axis and then you don't need to create a "functionAsModel":
| diag f | diag := ESDiagramRenderer new. (diag lineDiagram) y: [:x | x*x]; yAxisLabel: 'X^2'; rotatedLabels: true; regularAxis; defaultColor: Color green; models: (0 to: 10 by: 0.1). diag open On Thu, Mar 22, 2012 at 2:31 PM, Alexandre Bergel <[hidden email]> wrote: I would love to have a Pharo-based solution for doing numerical analysis.

In reply to this post by abergel
There is pdf framework under development (I saw some nice demos it will be open-source) so this means that we could have EyeSee to output pdf.
I really think that pushing EyeSee to provide model that after can be drawn in different format is the way to go else we will bind the model to the layout/output.
