#cGauge

Introducing yet another canvas gauge / jQuery plugin!

Usage

###Conventional Implementation

    value: 71,
    outerNums: false
};
var gauge1 = new cGauge(options1);

###jQuery Implementation

var options2 = {
    unit: 'Bananas',
    value: 17,
    maxValue: 50
};
var gauge2 = $('#gauge2').cGauge(options2);

Options

There are many options to mess with in cGauge, here is a list of all of them along with the default values.

var defaultOptions = {
  unit         : '',
  title        : '',
  titleOffset  : [0, 0],                    // [x, y] offset, numbers only
  valueOffset  : [0, 0],                    // [x, y] offset, numbers only
  gaugeOffset  : [0, 0],                    // [x, y] offset, numbers only
  fontSize     : '',                        // you must specify units i.e. '12px'
  valueFontSize: '',                        // defaults to fontSize if fontSize is defined
  titleFontSize: '',
  unitFontSize : '',
  perimFontSize: '',
  font         : 'sans-serif',              // font-weight, style may be specified like 'Arial Bold', you must spcify the font-name to do this, 'sans-serif Bold' will not work for unknown reason. 
  valueFont    : '',                        // defaults to font
  titleFont    : '',                        // defaults to font
  unitFont     : '',                        // defaults to font
  perimFont    : '',                        // defaults to font
  value        : 0,
  min          : 0,
  max          : 100,                       // actually defaults to function findGoodMax(value);
  arcColor     : '#27AE60',
  arcWidth     : 1,
  fillColor    : 'rgb(230, 230, 230)',
  fontColor    : 'rgb(80, 80, 80)',
  tickColor    : 'rgb(80,80,80)',
  outerSpace   : 0.4,
  innerSpace   : 0.4,
  ticks        : 40,                        // If not evenly divisible by 4, long ticks will be omitted.
  perimNums    : true,
  minNum       : true,
  maxNum       : true,
  noShadows    : false,
  shadow1: {                                // Shadows are ordered 1-4 from outermost to innermost,
    size : .15,
    color: 'rgb(155, 155, 155)'             // Must be rgb or hex code, css color-names will not work.             
  },
  shadow2: {
    size : .15,
    color: 'rgb(155, 155, 155)'
  },
  shadow3: {
    size : .15,
    color: 'rgb(155, 155, 155)'
  },
