Chartify

Chartify is an open source jQuery plugin for visualization using Google Charts. It makes charts from tables!

Chartify currently supports bar charts (including stacked and grouped bar charts), pie charts, Venn charts and a simple diagram for displaying gender distributions

Why should I use this?

• The approach of parsing actual html tables makes the data available in an accessible format to people (and search engines) who can’t experience visualizations for various reasons.
• It’s easier to use than any alternatives that we have seen. E.g.: $(’table’).chartify(’pie’);

4. OPTIONS

When called without an options parameter, the following defaults are used.

var settings = {
	chartWidth:     496, // in pixels
	chartHeight:    180, 
	marginTop:      0,
	marginRight:    0,
	marginBottom:   0,
	marginLeft:     0,
	legendWidth:    0,
	legendHeight:   0,
	pieChartRotation: 0,  // in radians
	unit:           '',   // appended to labels and values
	textSize:       11,
	textColor:      "666666",
	colors:         ["ff9daa","ffc000","007ec6","433840","6cc05c","ff710f","ED1F27","95a8ad","0053aa"],
	xAxisBoundaries:'auto',
	xAxisStep:      'auto',
	axisTickSize:   5,
	showLabels:     true,
	showLegend:     true,
	legendPosition: '',
	isStacked:      false,
	isDistribution: false,
	barWidth:       20,
	barSpacing:     2,
	groupSpacing:   10,
	imageClass:     ''
};

To override any of these defaults for a single call to chartify, use the options parameter.

To override any of the default settings globally, i.e. for all subsequent calls to chartify, use thesettings method:

$().chartify('settings', {showLegend: false});

When called without the parameter, the settings method returns the current default settings hash.
