Looking for help making a simple color-updating script!

Hey, I am looking for an Applescript that will conditionally format my Graffle based on colours. It seems like it should be doable, and useful… So I think it isn’t a terrible guess that someone has already done it!

Specifically, I want it to colour all objects of a particular shape depending on the number inside of that shape. It is going to be used on an iteration of this document: http://hockey.dobbersports.com/Top-100-Roto/top-100-roto-april-2014

I already have a script to transfer an excel file into the form you see there, changing the colours manually is the only tedious labor left.

Thanks a ton for any and all help!

Updated with a more accurate title. This should be relatively easy.

421 days later :-) ( some coding elements, in JavaScript for Applications, for reference )

Example: setting the background color of each circle on the canvas according to the number in the circle’s text.

(here, choosing one of 8 colors, ordered by saturation (taken from ColorBrewer), to match the position of the number on a scale 1-100)

(function () {
    'use strict';

    // TESTING: write a random number (in given range)
    // into the text of a shape
    function numberShape(shp, min, max) {
        min = min || 0,
            max = max || 100;

        var n = Math.floor(Math.random() * (max - min + 1)) + min;

        shp.text = n.toString();
    }

    // Choose, from a set of ordered colors of arbitrary length
    // the color corresponding to the position of a number within a range
    function numberColor(n, min, max, lstColors) {
        var lngColors = lstColors.length,
            i = Math.ceil(((n - min) * lngColors) / (max - min)) - 1;

        return lstColors[
            (i >= 0) && (i <= (lngColors - 1)) ? i : 0
        ];
    }

    // rewrite a triple of integers (0-255)
    // as a triple of reals between 0 and 1
    function rgb(r, g, b) {
        return [r / 255, g / 255, b / 255];
    }

    var og = Application('OmniGraffle'),
        ws = og.windows.whose({
            _not: [{
                document: null
            }]
        }),
        w = ws.length ? ws.at(0) : undefined,
        cnv = w ? w.canvases.at(0) : undefined;

    // A range of 8 colors taken from http://colorbrewer2.org/
    var lstPalette = [[1, 0.9607843137254902, 0.9215686274509803], [
        0.996078431372549, 0.9019607843137255, 0.807843137254902], [

        0.9921568627450981, 0.6823529411764706, 0.4196078431372549], [
        0.9921568627450981, 0.5529411764705883, 0.23529411764705882], [
        0.9450980392156862, 0.4117647058823529, 0.07450980392156863], [
        0.8509803921568627, 0.2823529411764706, 0.00392156862745098], [

    // TO TEST CODE BELOW:
    // PLACE RANDOM NUMBERS 1-100 IN EACH CIRCLE ON THE CANVAS
    var lstShapes = cnv.shapes.whose({
        _match: [ObjectSpecifier().name, "Circle"]
    }).callAsFunction().map(function (x) {
        numberShape(x);
        return x;
    });

    // MAIN: setting the fill color according to the number in the text
    // RANGE OF EXPECTED NUMBERS ?
    var min = 1,
        max = 100;

    // TYPE OF SHAPE CONTAINING NUMBERS ?
    var strShapeType = "Circle";

    // PROPERTY OF SHAPE TO BE COLORED ?
    var strColorProperty = 'fillColor';  // or 'strokeColor' etc


    // DEFINE A SET OF SHAPES, AND ITERATE THROUGH IT
    // CONDITIONALLY SETTING A COLOR PROPERTY 
    cnv.shapes.whose({
        _match: [ObjectSpecifier().name, strShapeType]
    })() // call the reference as a function to get an array
    
    // and iterate through the array setting fill colors by number
    .forEach(function (shp) {    
        shp[strColorProperty] = numberColor(
            parseFloat(shp['text']()), 
            min, max,
            lstPalette
        );
    });
